Abstract

A radar sensor for motor vehicles includes: a transmit and receive component, which includes a mixer for mixing a transmitted signal with a received signal; an evaluation circuit which is connected to an output of the mixer by a direct voltage coupling device; and a compensation device for compensating a DC offset in the output signal of the mixer, the compensation device being subdivided into a rough compensation device in the transmit and receive component, and a fine compensation device in the evaluation circuit.
