Radar detects objects using electromagnetic waves. A radar sensor contains a radar transmitter and a radar receiver. The electromagnetic waves generated by the radar transmitter propagate towards the target object at (approximately) the speed of light. There they are reflected and then received again by the radar receiver. The time difference between transmission and reception results in the distance traveled.

Echo curve
The echo curve (a) for a radar sensor shows the signal strength of the received echo signal in relation to the distance to the
reflecting target object in the vicinity of the sensor (Flied of View).
Depending on the application or objects in the field of view, one or
several peaks can occur within the echo curves. To visualize these
visualize these, Kübler offers a Graphical User Interface (GUI).

Kübler radar sensors – product series
Radar sensors in compact design RAD5xx
- Maximum compactness with M30 thread
- Measuring accuracies up to ±1 mm
- Opening angle ±3° or ±8
- Different measuring ranges between 0.15 and 40 m
- Analog interface with 3 additional switching outputs
Maximum signal strength
Mounting bracket for optimum alignment of the sensor to the application
Precise alignment of the sensor to the measurement object is crucial for optimum measurement results. The maximum signal strength of the reflected radar wave is achieved by aligning the radar sensor at right angles to the surface of the measurement object. Especially with a narrow aperture angle, the tolerances for a deviation from the vertical are relatively small in order to receive a signal at all.
For quick and precise alignment, corresponding mounting brackets are available for the RAD5xx series.
RAD5xx series, either for rotation about one or two axes perpendicular to the measuring direction.
Angle reflector for optimizing the signal strength in the application
Uneven surfaces or problematic focusing on a target object at a greater distance can strongly influence the signal strength of the radar signal to be received. Angle reflectors can help to increase the signal strength for greater measurement accuracy.
- Increasing the signal strength received from a target.
- Increasing the possible angle between the sensor
and the target.
Angle reflectors "bundle" the radar signals over a larger area. The geometry is designed so that reflections at any point (b+c) travel the same distance to and from the sensor as the direct reflection (a) at a 90° angle.

ConfigBox for easy visualization of the echo curve as well as
Setting the parameters and filter functions
For transferring the sensor data to a PC/laptop. After connecting the sensor to the PC via the ConfigBox, the configuration software is opened via the browser.
The software can be used to configure the sensor to the respective
application requirements or to check its status during operation. In addition to the visualization of the echo curve, the following settings can be configured:
- Configuration of the analog interface
- Setting the switching points for the switching outputs
- Setting the measuring range
- Definition of the signal threshold value
- Selection of the desired signal for multiple peaks
- and much more.
