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.
Claims11
A method for detecting precipitation using a radar sensor which emits a transmission signal whose frequency is varied periodically in successive modulation ramps, the method comprising:
- analyzing signals received by the radar sensor on two different criteria, wherein a first criterion relates to signals received during a pass-through of a modulation ramp, and a second criterion relates to a comparison of signals received during a pass-through of at least two successive modulation ramps.
A radar sensor for vehicles operating according to a method using successive modulation ramps for periodic frequency modulation of a transmission signal, the sensor being configured to perform the steps of:
- analyzing signals received by the radar sensor on two different criteria, wherein a first criterion relates to signals received during a pass-through of a modulation ramp, and a second criterion relates to a comparison of signals received during a pass-through of at least two successive modulation ramps.
