Zusammenfassung:	The present disclosure relates to vehicle radar system (3) comprising at least one transceiver arrangement (10a, 10b) and at least one control unit (29). Each transceiver arrangement (10a, 10b) is arranged for generating and receiving FMCW (Frequency Modulated Continuous Wave) chirp signals in a radar frequency band, comprising ramps (r1, r2) that each has a start frequency (fstart) and a stop frequency (fstop). Said control unit (29) is arranged to:Control at least one transceiver arrangement (10a, 10b) to monitor a certain part of the radar frequency band during an observation period.Analyze possible interference signals (28, 5c).Identify a certain start time (t2start) to start sending a cycle of one or more chirp signals (4a, 4b) in dependence of said analysis, such that interference from said interference signals (28, 5c) is reduced.The present disclosure also relates to a corresponding method.
