1. A method for suppressing interference in a radar transceiver, the method comprising the steps of:
transmitting a radar signal at a frequency F (t),
receiving a radar signal,
monitoring frequencies adjacent to the frequency F (t) for an interference, and, if the interference is detected in the adjacent frequencies,
determining a cross-over time duration for the interference in advance of an end of the interference, and
pausing radar signal transmission for the cross-over time duration,
wherein the transmitting comprises the steps of transmitting a frequency modulated continuous wave radar signal having the frequency F (t), and
wherein determining the cross-over time duration comprises determining a relative frequency gradient between the transmitted radar signal and an interfering radar signal.
