Abstract

A method for detecting precipitation using a radar sensor system for motor vehicles designed for locating objects in the surroundings of the vehicle, in which method a locating signal that is a measure of the received power density as a function of the distance is integrated across a specific distance range lying below a limit distance for detecting precipitation. The locating signal is subjected to a filtering procedure before being integrated, the filtering procedure suppressing the peaks caused by located objects so that the filtered signal forms a measure of the noise level as a function of the distance.
