Abstract:
Method and system of calibrating a sensor system which comprises sensor A and sensor B. Sensor A has a transmitter TXA for emitting a signal STXA and a receiver RXA for receiving a signal SRXA, wherein RXA and TXA operate independently in a radar mode of sensor A. Sensor B has a transmitter TXB, a receiver RXB, and a unit D, which is used to connect TXB to RXB in a transponder mode of sensor B, with the result that a signal SRXB received by RXB is emitted again by TXB as a signal STXB. A gain Gcon,B between signal SRXB and signal STXB is predefined. In a radar mode of sensor B, TXB is not connected to RXB, with the result that TXB and RXB operate independently. Emitted signals may be radar, light, or acoustic signals. The method and system can calibrate radar systems, lidar systems, or sonar systems.
