ABSTRACT:
A radar sensor emits microwave radiation and receives partial radiation reflected at objects within the sensor detection range, a plurality of antennas being provided for the transmission and reception in each case, and the transmission power of the outer antennas being lower than the transmission power of the inner antennas. This is accomplished by reducing the transmission power with the aid of couplers, the couplers advantageously being implementable as Wilkinson power splitters.
