Abstract
A signal-processing method for a motor-vehicle radar arrangement is specified, which method provides more extensive information on the traffic situation in observation direction by evaluating echo signals deflected at the road surface.
Claims10
A signal processing method in a motor-vehicle radar arrangement, comprising the following steps:
- emitting radar signals in the direction of motor-vehicle travel, said radar signals reflecting at least one of a road surface and a reflecting target adjacent the road surface resulting in echo signals;
- and
- evaluating echo signals which correspond to a signal path with a diversion at the road surface between the radar arrangement and the reflecting target adjacent the road surface;
- wherein at least one of a signal emission or signal reception is performed selectively into the road surface or from the road surface, respectively.
