3 Radar Tutorial
This chapter gives you a concise overview of radar technology, covering its key principles and practical applications.
You'll gain an understanding of how radar sensors operate and the various factors that influence their performance
3.1 Distance Measurement with Radar
Radar operates by emitting electromagnetic waves, which travel through the air at nearly the speed of light. When
these waves encounter an object, they are reflected back towards the radar sensor. By analyzing the time delay and
the frequency shift of the reflected waves, the radar sensor can accurately determine the distance and velocity of the
object. This technology ensures precise and reliable measurements, making radar sensors essential for various
applications.
Distance measurement with electromagnetic waves
3.2 Radar penetrates non-conductive Materials
Radar sensors can penetrate non-conductive materials such as plastic, rubber, cardboard, glass, and similar
substances because radar waves are only partially reflected by these dielectric materials. Conversely, when radar
waves encounter metals or closed water surfaces, they are fully reflected. This ability to penetrate certain substances
or objects makes radar distance sensors highly versatile and suitable for a wide range of applications.
Material Penetration Description
Metal
Impossible
Water/ water film Impossible in case of a closed water surface. Water drops can be penetrated.
Concrete Difficult - depending on the thickness of the concrete
Wood Low - the penetration decreases for an increased humidity content of the
wood.
Plastic / rubber - Medium to high - depending on thickness as well as plastic or rubber type
Paper / cardboard
High - in case of low humidity content

Material Penetration Description
Glass High - depending on the material9s thickness.
Smoke / dust /
steam
High
Radar sensors can detect the distance to objects behind glass, plastic or other non-conducting materials. At the
interface of the dielectric material, there is a weak reflection, which allows for the determination of the distance to
the object. However, most of the radar waves radiate unhindered through this material, so that the distance to an
object that is positioned behind the dielectric material can be determined. To protect the radar sensor from
irradiation or explosions, glass, heat-resistant plastics or a mica plate can be used. Only a limited amount of the radar
signal is reflected, so that the radar sensor detects the distance to the object behind it with high accuracy.
Radar allows you to measure through non-conductive materials:
While water drops and high humidity, dust and smoke do not have a big impact on the radar
signal, closed water surfaces are more or less impossible to penetrate.
3.3 Opening Angle: Defining the Focus of the Radar Sensor
The measuring spot size of the radar distance sensor, influenced by the opening angle (or aperture angle), significantly
affects target detection and interference reflections. Imagine the radar signal as a flashlight beam: a poorly focused
flashlight illuminates a wide area but does not reach large distances, while a highly focused flashlight shines further
and more precisely on specific objects.
Similarly, for radar sensors, a larger aperture angle results in a larger measuring spot, increasing the field of view but
reducing measurement range and accuracy due to signal dispersion and interference. Conversely, a smaller opening
angle provides a smaller, more focused measuring spot, enhancing signal strength and accuracy.
The figure below illustrates how the opening angle affects measuring spot size and signal strength. A smaller opening
angle offers a stronger signal and higher accuracy.
Opening angle affects measuring spot size
Use the OndoSense radar spot size calculator to determine your sensor's measuring spot size based on distance.
Select your radar sensor from the list or input the opening angle and lens diameter for a calculation of the radar spot
size in relation to a certain distance to the target object.

Position the sensor closer:
Measure closer to the target to reduce the measuring spot size and minimize interference.
Small opening angle = Increased Focus:
A small opening angle reduces interference reflections and improves measurement
accuracy.
Opening angle and detection orientation:
A smaller opening angle limits the maxmimum tilt the target object can have against the
orientation of the sensor while still ensuring a stable signal output.
3.4 Radar Resolution and averaging across the Measuring Spot
Radar Resolution: Radar resolution is critical for determining how well a radar distance sensor can distinguish
between two closely spaced objects. It defines the minimum distance at which two objects can be separately detected.
If the radar signals (peaks) from these objects can be distinguished, their distances can be accurately measured, as
shown in the figure below.
Averaging across the measuring spot: When objects are positioned close together or surfaces have complex
structures, and the distances between reflection points are smaller than the sensor9s resolution, the sensor
automatically averages the distance values. This ensures stable, consistent measurements, even on uneven or
irregular surfaces. Stronger reflections are given more weight in the averaging process, leading to accurate and
reliable readings. By smoothing out the impact of surface irregularities, averaging enhances the sensor9s overall
performance. For more advanced applications, OndoSense can create customized radar algorithms to further improve
measurement precision.
If the radar signals (peaks) from these objects can be distinguished, their distances can be accurately measured. If the
peaks from these objects or an uneven surface cannot be distinguished, the distance is averaged across the measuring
spot as shown in the figure below.

Object Detection:
Radar resolution enhances the sensor's ability to accurately detect and distinguish objects
that are close to each other, ensuring reliable distance measurements for each individual
object.
Measurement Averaging:
When multiple reflection points are within the sensor9s resolution range, the sensor
effectively averages the distances, providing a consistent measurement even in complex
surface scenarios.

6.2 Standard Settings
6.2.1 Radar Signal set-up
First, align the sensor perpendicular to the target. Then use the spectrum view for final
adjustments. The smoother a surface, the more crucial the precise alignment of the radar
sensor becomes.
The signal strength received by the radar sensor is one of the most important factors to achieve reliable measurement
results. It is visualized by the amplitude of the spectrum in OndoNet. The signal strength increases when the sensor is
aligned perpendicular to the target of the measurement.
Correctly aligning the sensor to the measurement target also avoids unintended reflections by other objects. This
increases the signal strength and the Signal to Noise Ratio (SNR). Measurements with a high SNR are more robust to
external interference.
Another factor that affects the signal strength of the measurement is the roughness of the surface. The rougher the
surface, the higher the degree of tilting that allows for a stable radar signal. For smooth surfaces, the maximum
possible tilting is lower than for rough surfaces. In contrast to measurements with for example laser sensors, rough
surfaces are an advantage in measurements with radar sensors because the likelihood that a part of the beem is
refelcted back to the sensor is higher.
The figure below schematically shows the influence of the orientation of the sensor to the measurement target on the
signal strength reflected back to the sensor. Perfectly perpendicular targets reflect a stronger signal to the sensor.
With increasing tilting of the surface or object, the signal strength of the radar sensor decreases, as the radar
radiation is increasingly not thrown back to the radar distance sensor.
Align sensor perpendicular to target for better signal strength
Align the sensor towards the targe: Manually adjust the orientation of the sensor while monitoring the signal
strength displayed in the configuration software. All detected objects and their signal strength are displayed in the
<Spectrum= chart, which is positioned below the <Target= chart.
To monitor the signal strength while adjusting the sensor alignment, click on
FIX SCALE and ADD HOLD for the
magnitude in the spectrum chart. This way you can monitor whether your adjustment leads to an increase or a
decrease of the signal strength. Continue until the optimal signal strength is reached.
If your target is too far away or the signal strength remains low, consider using a
radar reflector to enhance the signal
and improve detection accuracy.

AutoGain: Once you are done, click on AUTO GAIN in the <Settings= section to further optimize the signal strength.
This will automatically adjust the gain parameters of the amplifiers.
If you have a changing distance to the target, please refer to the
Raw Data chapter.
6.2.2 Peak Selection
Select your peak by "Amplitude" if your target is characterized by the strongest signal.
Choose "Distance" if your target is expected to be the closest peak.
With the Peak Selection feature, you can choose which peak you want to use in the measurement. The selected peak
is indicated by the red line (a) in the spectrum view shown in the figure below. You can choose between the following
options (g) :
Distance: Peak with the closest distance within the measurement distance (b)
Amplitude: Peak with the highest amplitude (a)
Normalized amplitude: Target with the highest Radar cross section.
Distance backwards: Last peak by distance (d)
Amplitude backwards: Last peak by amplitude (d)
Normalized amplitude backwards: Target with the smallest Radar cross section.
6.2.3 Measurement range
Limit the measurement range to the specific area of interest for your application.
The Measurement Range should be limited to the area of interest. It is the most effective way to avoid undesired
interference signals from the surroundings. It can be changed in the Settings panel on the right (e) . To save the
changes use the set button. The values do not get saved automatically.
The first peak shown in the spectrum below is the self-reflection of the sensor (b). As it comes from the sensor itself
and not from the target it should not be taken into account during the measurement. This can be avoided by adjusting
the lower end of the measuring range to a higher value.
If you know the object you want to measure the distance to will always be located at a distance between 1m and 5 m,
it is recommended to limit the measuring range to approximately 0.8m and 5.2 m. Any signals originating from objects
at distances below the minimal distance or above the maximum distance will be ignored, leading to more robust
measurement results in production.

6.2.4 Adjust the Threshold
Setting a threshold can increase the robustness of the measurement, but can also lead to
false negatives if set too high.
Setting a threshold is an effective way to improve the measurement robustness by suppressing targets with a lower
signal strength than the signal of interest. This increases the robustness of the measurement significantly. The
threshold (in amplitude) is indicated by the orange area in spectrum view (c) in the figure below and can be adjusted by
changing the value in the Threshold field (f) . Only peaks with a signal strength above this threshold (a) are considered,
all others are suppressed (d) .
To find the right threshold for your application first position the sensor perpendicular to the target such that the
signal amplitude is maximised. Choose a target that is located at the maximal measurement distance. Then set the
threshold approximately to 30% of the lowest signal strength. Monitor the measurement for a while to guarantee that
the signal strength is never close to the threshold. In a case of doubt, it is always better to set the threshold lower. Be
careful with using this feature for collision avoidance applications as a high threshold can lead to false negatives.

6.3 Advanced Settings
6.3.1 Filter and Smoothing
To ensure smooth and accurate measurements, applying filter or smoothing algorithms can
be beneficial. To disable the filters, set the values to 0.
Filter
The filters helps reduce sudden jumps in distance measurements, which can be caused by unwanted reflections not
coming from the primary target. These jumps typically occur when the sensor's alignment to the main target is
momentarily disrupted.
Maximum Distance: Set the maximum distance parameter to a value that represents the largest realistic difference
between two consecutive measurements for your application. This ensures that only plausible changes in distance are
accepted, while any distance differences exceeding this value will trigger the filter.
Maximum Time: Set the maximum time parameter to define the duration after which a new value should be accepted,
even if an unrealistic distance jump occurred.
How the Filter Works:
Triggering the Filter: The filter is activated when a sudden change between two consecutive measured
distance values exceeds the defined maximum distance change.
Output During Filtering: The sensor will continue to output the previous stable measurement until one of the
following conditions is met:
Restoring the Original Level: The measured distance change returns to within the previous value ± the
maximum distance change. At this point, the sensor will start displaying the new measured value.
Maximum Time Reached: If the maximum time limit is reached before the original level is restored, the
sensor will start displaying the new measured value.
By setting the parameters for maximum distance and maximum time, you ensure the sensor ignores erratic
measurements and provides more stable and accurate readings.
The following figure is a simplified representation of the Target view, where x represents time and y represents the
measured distance. The events a, b, and c illustrate jumps in the measurement values and how they are managed by
the filter.
The filter is not triggered because the change in distance between two consecutive values does not exceed the max
distance parameter.
The filter is triggered because the max distance is exceeded. The filter is then deactivated as the value returns to
the original level.

The filter is triggered because the max distance is exceeded. The filter is deactivated because the max time limit is
reached, and the value is adjusted to the new measured distance.
Filtered measurement events
Smoothing
Smoothing applies exponential averaging to the measurements, which is useful for stabilizing fluctuating distances to
the target. This is particularly helpful in dynamic applications, such as monitoring filling levels.
The averaging time affects the time frame over which the exponential averaging is applied and specifies that 95% of
the output distance come from the new distance value.
The larger the averaging time, the slower the sensor adapts to new distance values, resulting in a more smoothed
output. This means that sudden changes in distance are less immediately reflected in the measurements, providing a
more stable reading at the expense of responsiveness. A shorter averaging time allows the sensor to respond more
quickly to changes in distance, reflecting new values more rapidly but with less smoothing, which may result in a more
fluctuating measurement.

6.3.2 Distance Offset
The distance offset will be automatically added to all distance measurements, ensuring that
the displayed distance values are accurate and reliable for your specific application.
The distance offset is a value that is added to the measured distance value to adjust for any systematic measurement
errors or specific application requirements. By setting an appropriate distance offset, you can ensure that the sensor
readings accurately reflect the actual distance to the target. This adjustment is particularly useful in scenarios where
the sensor cannot be placed at the optimal measurement point or where inherent measurement biases need to be
corrected.
To configure the distance offset, enter the desired value in the offset field. This value will be automatically added to all
distance measurements, ensuring that the displayed distance values are accurate and reliable for your specific
application.
Distance offset
6.3.3 Background Calibration
The Background calibration is only useful for applications in which the surrounding is static
and the sensor is not moved throughout the measurements
In some applications it may be useful to set a background calibration on the sensor. This is recommended, for example,
if measurements are to be taken in a highly reflective environment and the reflections not required for the
measurement are to be masked out.
The background calibration takes a "snapshot" of the signals visible in the spectrum and subtracts these signals for all
measurements done after the calibration. Therefore, this setting is only useful for applications in which the
surrounding is static and the sensor is not moved throughout the measurements.
To set the background calibration please do the following:
Measurements with the measurement object:
Before you start setting the background calibration, position your measurement object at a medium distance
within the measuring range. Please make sure that the sensor is positioned correctly, the measuring range and

the parameters in the raw data view are set appropriately. These cannot be easily changed after the
background calibration is set. It must also be ensured that the sensor has been placed firmly, i.e. it should not
be moved by vibrations or similar.
Remove the measurement object:
The goal of the background calibration is to subtract all signals originating from a static background in
order to isolate the signals originating from the measurement object. Therefore, to take a "8snapshot"9 of
the background, please move the measurement object out of sight of the radar sensor.
Setting the background calibration:
After removing the measurement object, start setting the background calibration by clicking on the
CALIBRATE button in the settings panel on the right and confirm it.
Measurements with the measurement object:
The background calibration is completed and you can now take measurements with the measurement
object in sight of the sensor. The amount of signals visible in the spectrum view should be decreased
compared to the amount of signals that were visible before the background calibration was set.
After successful calibration you will see a label <calibrated= above the individual views. Also, all amplifier
settings in the raw data view are disabled. If you want to change these parameters, please remove the
background calibration as described below, change the parameters and set the background calibration again.
After setting, it can take a few seconds until the sensor provides a good signal again. If your sensor is not firmly
positioned and is moved, for example, by vibrations, you will be able to recognize this in the signal. The signal
will then be very choppy and flicker.
Deleting the background calibration:
To delete the background calibration and thus reactivate the amplifier parameters in the raw data view, please click
on the
REMOVE CALIBRATION button in the settings panel on the right and confirm.

6.3.4 Threshold Sensitivity
The Threshold Sensitivity suppresses undesired signals close to the target signal.
The Sensitivity feature is recommended for weak signals. It can improve the measurement robustness by suppressing
undesired signals close to the target signal. The sensitivity calculation is based on an algorithm which identifies the
main peaks of a spectrum and suppresses side peaks. The result of this calculation can be seen in the figure below,

where the threshold is low at the peak, but significantly higher next to the peak. The strength of this effect can be
adjusted via the Sensitivity parameter.

6.3.5 Raw Data
Use the
AUTO GAIN button to optimize amplification parameters, significantly improving
signal quality and measurement robustness.
The Raw Data view shows the echo raw data for the sampled time domain. It contains information about the distance
and size of the target. The
AUTO GAIN button automatically optimizes the amplification parameters for your
specific application, significantly enhancing signal quality and measurement robustness. The suitable values of the
amplification parameters differ between measurements. Therefore, they should be adjusted during a typical
measurement.
If the target is in motion, it's recommended to click
AUTO GAIN when the target is positioned midway between its
maximum and minimum distances. If the furthest signal isn9t detected with the initial amplification, move the sensor
closer to the maximum distance and click
AUTO GAIN again to recalibrate. If maintaining accuracy at close range is
critical, configure
AUTOGAIN at a closer distance, accepting that distant targets may not be reliably detected.
Conversely, if distant targets are equally important, you might prioritize their detection and set
AUTOGAIN at a
further distance, even if it means accepting some clipping at closer ranges. Ultimately, the choice depends on which
distance is more critical for your application.
The graph should show a sinus function with high amplitudes. The images below illustrate examples of both correct
and incorrect settings. Optimal results are typically achieved when the curves range between -127 and +127,
ensuring that the peaks of the curves are not clipped.
Even with clipped signals, the robust OndoSense algorithms can calculate the correct distance, although the
measurement accuracy will be lower. If the signal received by the sensor is too weak for a meaningful measurement, a
<weak signal= label will appear above this view.

If AutoGain, in combination with all other correctly set parameters, does not yield the desired results, you can
manually adjust the ADC Amp Gain value incrementally while monitoring the raw data display. It is good practice to
use the same amplifier values for I and Q, so the amplification parameters are linked. If you want to adjust the
channels individually, click on the linked button.

The Current Interface can be configured on the IO Configuration page, just below the settings for the switching
outputs. Here, you can specify the distances in millimeters at which the current should be 4 mA and 20 mA, as
illustrated in the figure below. The interface will output a current that corresponds to the distance of the target, with
the current value linearly varying between the two defined distances.

6.5.2 Switching Outputs
If no target is detected, the output remains in its previous state.
Each of the switching outputs can be configured individually, as demonstrated for Output 1 in the figure below. Follow
these steps to set up your desired output:
Distance to Active (Point 1): Set the distance in millimeters at which the output should change to active.
Distance to Inactive (Point 2): Set the distance in millimeters at which the output should revert to inactive
(Window-Mode). For Single-Point mode, set this value to the maximum measuring range.
Hysteresis: Define a window in millimeters to adjust the switching point based on the previous state. This
helps prevent multiple switches if the target distance fluctuates around the switching point.
Mode: Choose between "Active High" (PNP-mode) and "Active Low" (NPN-mode) to set the output mode.
Active High (PNP-mode): In this mode, the output is considered active when it sends a positive voltage
(high state). This means that when the sensor detects the specified condition, it will switch to a high
voltage state.
Active Low (NPN-mode): In this mode, the output is considered active when it sends a negative
voltage or zero voltage (low state). This means that when the sensor detects the specified condition, it
will switch to a low voltage state.
Delay: Specify the time in milliseconds that the signal needs to be registered before switching to active.
Release: Specify the time in milliseconds that the signal needs to be registered before switching to inactive.

7 System Management & Maintenance
This chapter focuses on the effective management and upkeep of your sensor system. It includes instructions on
saving and loading settings and updating software and firmware.
7.1 IP-Adress Configuration
The IP-Adress of LAN port 2 of the ConfigBox can be configured via OndoNet.
This can be helpful to add the ConfigBox to an existing network or to make the measurement data available via OPC
UA.
To setup a fixed IP address:
Access OndoNet via LAN1 (10.10.42.1).
Click on
SENSOR MANAGEMENT in the navigation bar; click on the symbol in the IP Address column.
In the Pop-up, untick DHCP, enter the desired IP address, Subnet Mask & Default Gateway and Confirm.
Now the new IP address is configured for LAN2. OndoNet and the OPC UA server are now accessible via the
configured IP address. Simply enter the new IP address into your browser to launch the OndoNet interface.
For being able to access the ConfigBox via LAN port 2, the Ethernet port of the PC must be
configured with an IP address in the network address space as the IP address that was set.
For example if the IP address of the ConfigBox was set to "192.168.10.143", the IP address
of the PC needs to be set to "
192.168.10.xxx" with xxx being any number except for 143.

7.2 Save/Load Configuration
You do not need to save the settings after making adjustments. The sensor automatically
retains the configuration changes even if you disconnect it from the ConfigBox and connect
it to the PLC. The settings will remain stored on the sensor until you make further changes.
Saving the settings is only necessary if you want to create a backup or transfer the
configuration to another sensor.
After configuring your sensor to the desired settings, you can save these settings as a file. This saved configuration
can then be easily loaded onto another sensor or reloaded onto the same sensor at a later time.
Save Settings
Once you've configured the sensor, select the Save Settings option. The browser should start downloading a file
named <Date_Time_Sensor_Variant_Settings.os<.
Save Sensor Settings Panel
Load Settings
To apply a previously saved configuration, use the Load Settings option. Navigate to the location of your saved file and
select it. The sensor will then automatically apply the saved settings, replicating the exact configuration on either the
same or a different sensor. This process ensures consistency across multiple sensors and saves time when setting up
devices for similar tasks.
This functionality is particularly useful when working with multiple sensors in a network, ensuring that all sensors
operate with the same optimized settings, or when quickly reapplying configurations after maintenance or sensor
replacement.
