Abstract: 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.
