Targets in front of the sensor are reflecting the radar signal and the relative speed and distance is determined via Doppler-effect and beat frequency. The angular position of the target is determined by use of the normalized antenna diagram.

The sensor Radome points under an angle of approx. 40° relative to the vehicle driving direction, the connector points downwards. The outline dimensions of the sensor (without connector) are approx. 70x60x30mm3 (l×w×h, Category II): 40°±3° 40°±3° 40°±3° 40°±3° During the application of the sensor behind a bumper, special care must be taken in selecting the cover-material, cover shape, painting and position of the cover relative to the sensor. Water droplets, water film and snow sticking onto the bumper surface might cause additional attenuation that leads to a restricted performance or availability of the implemented functions and further systems.

The below diagram gives the usage of the TX antennas per measurement cycle: In the “TX” phases the sensor is transmitting via the TX1 or TX2 antenna, depending on the cycle. In the “calculation” phase the sensor is receiving signals and processing the received signals. The value for “TC” is 120ms. 9.4.2 TX antenna configuration The antenna structure of the sensor contains 2 TX antennas, with a pattern as described in chapter 8.1. In Azimuth, the main lobe of the TX antennas is rotated +/- 20degrees with reference to the center axis of the sensor (0degrees reference). To generate the required field of view for the sensor performance, both TX antennas are arranged mirror inverted on the radar pcb in the device. Through this arrangement the total resulting antenna opening angle is appox. 50degrees with a minimum at the center axis (0degrees reference) of the sensor. Page 21 of 21
