A vehicle radar system () having at least one transceiver arrangement () arranged to generate, transmit and receive reflected radar signals. The transceiver arrangement () includes an ADC arrangement () that is arranged to output a digital IF signal () in a time domain to a DSP arrangement (). A first DSP function (a) is arranged to: identify and retain sample points of the digital IF signal () in a spectral domain with signal components that exceed a certain level threshold, such that an approximation signal () is formed in the time domain, identify possible sections () of the digital IF signal () in the time domain that exhibit interference exceeding an interference threshold, determine whether or not to replace such sections () with equivalent sections () of the approximation signal (), and if applicable, replace such sections () with equivalent sections () of the approximation signal ().

Vehicle radar system arranged for reducing interference

A system and method for mitigating interference in a frequency-modulated continuous-wave radar processing system is defined. Random inter-pulse jitter is implemented in a transmitted radar signal to prevent identification of false tracks due to interfering radar signals. Random intra-pulse jitter of time and/or frequency is implanted to create spreading of false targets and provide a method to distinguish false targets from true targets. Adjacent sensors in a multi-sensor radar system are alternatingly configured to transmit either upward ramping or downward ramping frequencies to mitigate interference between adjacent sensors in the same radar system.
