Abstract: An automotive radar system and method transmit a plurality of radar signals into a region, detect reflected radar signals, and convert the reflected radar signals into digital data signals. A plurality of range-Doppler maps for the region are generated from the digital data signals, and the plurality of range-Doppler maps are averaged to generate an averaged range-Doppler map for the region. Data points in the averaged range-Doppler map are analyzed to detect blobs in the averaged range Doppler map. If a blob is detected in the averaged range-Doppler map, the radar detector is indicated to be unblocked.

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.
