摘要:
The radar sensor has a transmission and reception device (11) for producing a radar signal at an adjustable output power (P), a control device (12) and an interface unit (13). The interface unit (13) and the control device (12) can be used to control the transmission and reception device (11) via a digital interface (23). The radar sensor is distinguished in that one of the lines of the interface (23) is connected to the control device (12), wherein the control device (12) is designed such that when a predetermined level is present on this line the output power (P) of the transmission and reception device (11) is lowered.
