A radar sensor for motor vehicles, having a transmitting part, which has two oscillators and a 90° phase shifter for generating a transmission signal, a first comparison signal, and a second comparison signal, which is phase shifted by 90° with respect to the first comparison signal, and a receiving part having an I mixer for mixing a received signal with the first comparison signal and a Q mixer for mixing the received signal with the second comparison signal, in which the transmitting part has a first transmit mixer, whose inputs are directly connected to the two oscillators, and a second transmit mixer, whose one input is directly connected to a first of the two oscillators and whose other input is connected via the phase shifter to the other oscillator. |
