Zusammenfassung:The present disclosure relates to a vehicle radar system (3) comprising at least one transceiver arrangement (7) arranged to generate and transmit radar signals (4), and to receive reflected radar signals (5). The transceiver arrangement (7) comprises an ADC, Analogue to Digital Converter, arrangement (10) that is arranged to output a digital IF, Intermediate Frequency, signal (20) in a time domain to a DSP, Digital Signal Processor, arrangement (12). A first DSP function (12a, 12a') is arranged to: - Retain sample points of the digital IF signal (20) in a spectral domain with signal components (F(0), F(1), F(2)) that comprise a defined group of frequency components falling below a certain frequency threshold. - Reconstruct a possible time-domain fascia interference signal (51) comprised in the digital IF signal (20) from said signal components (F(0), F(1), F(2)). - If applicable, subtract said time-domain fascia interference signal (51) from an input digital IF signal (20, 20').
