摘要： A vehicle impact detection sensor for providing an input variable for an activation logic unit or for generating an activation signal for an active occupant protection system, has a radar transmitter and a radar receiver which are arranged on a sensor-carrying superstructure of the vehicle. The radar receiver receives radar waves which are emitted by the radar transmitter and reflected at an impact-relevant reflexion surface that moves relative to the sensor-carrying superstructure in the event of an impact. A Doppler frequency evaluation unit uses the frequency of the transmitted radar waves and the frequency of the radar waves reflected from the impact-relevant reflexion surface to determine the associated Doppler frequency and detects therefrom a relative movement of the impact-relevant reflexion surface with reference to the sensor-carrying vehicle superstructure. The impact-relevant reflexion surface is a surface permanently connected to the vehicle, preferably, an outer surface of the vehicle.
