Abstract
The invention relates to a method for suppressing interference in a received signal (s) received by a radar sensor (5, 6) of a motor vehicle (1), wherein for detection of a target object (12) in an environment of the motor vehicle (1), a transmit signal including a sequence of consecutive frequency-modulated chirp signals is emitted by means of the radar sensor (5, 6) and an echo signal reflected on the target object (12) is received as the received signal (s) with the superimposed interference, and wherein after receiving the received signal (s) by the radar sensor (5, 6), the interference of the received signal (s) is detected and suppressed by means of an electronic computing device. At least two signal correction algorithms different from each other for suppressing the interference are stored in the computing device, and the control device selects at least one of the at least two signal correction algorithms depending on the detected interference in order to suppress the interference in the received signal (s).
