2. General information
The SRR5-B sensor measures independently the distance and velocity (Doppler's principle) to objects without
reflector in one measuring cycle on the basis of FMCW (Frequency Modulated Continuous Wave) with very fast
ramps. A special feature of the device is the simultaneous measurement of large distances up to 99 meters,
relative velocities between ±300 km/h and the angle relation between two objects.
The sensor is mounted in the front or rear corner of the car behind the bumper, as illustrated in Figure 1.

The sensor performs in alternation a Short Range (SR) Scan cycle and a Far Range (FR) Scan cycle. The Short
Range Scan covers distances up to 12.6 meters and angles of ±90 degrees in front of the sensor. The Far
Range Scan covers distances up to 99 meters with angles of ±90 degrees.
The sensor allows a detection of objects in the given Field of View (FoV) and evaluates the current constellation
under consideration of all detected objects and among others the following information:
➢ Vehicle Dynamics Data (e.g. Velocity, Acceleration, Yaw Rate of the host vehicle) which is transmitted to
the sensor from the car via the vehicle bus
The sensor SRR5-B is designed for comfort/safety applications in passenger cars and trucks like Blind Spot
Detection, Rear Cross Traffic Alert (with braking), Lane Change Assist, Trailer Detection
In dependence of the overall information the sensor outputs specific messages, which may then be used by
other vehicle components (braking system, power train, door modules etc.).
