METHOD FOR OPERATING A RADAR SENSOR OF A MOTOR VEHICLE, DRIVER ASSISTANCE DEVICE AND MOTOR VEHICLE

摘要

The invention relates to a method for operating a radar sensor (5, 6) of a motor vehicle (1), in which for detecting a target object (12) in an environment of the motor vehicle (1), a transmit signal (S) is emitted by means of the radar sensor (5, 6) and an echo signal reflected on the target object (12) is received as a received signal, wherein a plurality of sequences (13) each including a plurality of frequency-modulated chirp signals (14) is emitted one after the other by means of the radar sensor (5, 6) as the transmit signal (S), and wherein a transmission pause (15) respectively follows each sequence (13), in which the radar sensor (5, 6) does not emit any chirp signals (14). The period of time of the transmission pauses (15) is respectively randomly adjusted in the operation of the radar sensor (5, 6).
