Abstract
In the method for detecting precipitation using a radar sensor, the radar sensor emits a transmission signal, whose frequency is varied periodically in successive modulation ramps. Signals received by the radar sensor are analyzed to determine precipitation on the basis of two different criteria. In the method, a first criterion relates to signals which are received during a pass-through of a modulation ramp, and a second criterion relates to a comparison of signals which are received during a pass-through of at least two successive modulation ramps.
