Abstract

A radar sensor is described. The radar sensor includes at least two synchronously operating high frequency components, which each have at least one signal path in which the phase of the transmitted high frequency signal is varied by a temperature-dependent phase difference. In each high frequency component, a phase detector is connected in parallel to the signal path, which supplies a signal that assumes an extremum at a certain phase difference independently of the temperature, and a phase shifter is situated in the signal path, ith the aid of which the phase difference is settable in such a way that the signal of the phase detector assumes the extremum.
