Abstract
A system for monitoring a traffic situation includes at least one radar sensor unit for recording environmental data in a monitoring region of the radar sensor unit. A central processor evaluates the environmental data from the radar sensor unit and determines the traffic situation within the monitoring region based on the environmental data. A reference signal unit for outputting a reference signal to the radar sensor unit is configured to modulate a radar signal emitted by the radar sensor unit and to reflect a modulated radar signal back to the radar sensor unit as a reference signal. The processor identifies the modulated radar signal as a reference signal from the reference signal unit and recognizes a malfunction of the radar sensor unit if a reference signal is not received by the radar sensor unit.
