Abstract

A method for detecting precipitation using a radar locating device for motor vehicles, that is designed to locate objects in the surroundings of the vehicle, in which method a locating signal (42), which is an index for the received power density as a function of the distance (R), is integrated over a first distance range (INT1), which is below a limit distance (Rlim) for the detection of precipitation, wherein the locating signal (42) is additionally integrated over a second distance range (INT2), which is above limit distance (Rlim), and for the detection of precipitation, the integrals over the first and second distance range are compared with each other.
