Location
Front:
The DISTRONIC (DTR) sensors are inserted from the rear at the left and right respectively into the front bumper.

Rear:
The radar sensors are respectively inserted on the inside on the left and right outer side for the rear bumper.

Task
The radar sensor or the DTR sensors (short range sensor) recognize objects (e.g. vehicles) in the short range area up to s = 30 m for a maximum detection angle of Angular= 130°.

Design
The radar sensors or the DTR sensors are ultra-wideband radar sensors with the following properties:
- Radar sensor detection range s = 0.18 to 30 m, at a resolution of s = 0.04 m
- Acquisition angle Angular = 60° with angle determination and Angular = 130° only detection (track)
- Radar sensor with f = 24.125 GHz carrier frequency
- Method of operation: short pulse method with f = 5 GHz band width

The high band width of the radar sensors or the DTR sensors allows a very precise position statement to be made and optimizes separation of objects lying close to each other.

Coding (differentiation) for the individual radar sensors takes place by means of different assignment with ground on pin 5 and 6.

The radar sensor or the DTR sensors are actuated and evaluated by the following control units via the sensor CAN (CAN S):
- Radar sensors control unit (N62/1) (up to 31.5.11)
- Video and radar sensor system control unit (N62/2) (as of 1.6.11)
