| 主权项 | 1. A radar sensor for motor vehicles, comprising: a coupling device; a transmit-and-receive component including: a mixer for mixing a transmitted signal with a received signal; anda rough compensation device for compensating a first DC offset in an output of an output of the mixer; and an evaluation circuit to which the output of the mixer is forwarded via the coupling device, wherein the evaluation circuit includes a fine compensation device for compensating a second DC offset, and wherein the coupling device is adapted for conducting direct voltage. | ||
