Abstract
A method for detecting interference in a received signal received by a radar sensor of a motor vehicle is disclosed. For detecting a target object in an environment of the motor vehicle, a transmit signal is emitted by the radar sensor, which includes a sequence of consecutive frequency-modulated chirp signals. The radar sensor then receives an echo signal reflected on the target object as the received signal with the superimposed interference. After receiving the received signal, the interference in the chirp signals of the received signal is detected.
