Abstract
The description below relates to a method for a radar system that can be used to detect perturbations in the received radar signal. According to an example implementation, the method comprises providing a digital radar signal using a radar receiver, wherein the digital radar signal comprises a multiplicity of segments; calculating an envelope signal that represents the envelope of a segment of the digital radar signal; and ascertaining a time of the onset of an interference signal contained in the considered segment of the digital radar signal by using at least one statistical parameter of the envelope signal.
