Distributed Radar Signal Processing in a Radar System

Abstract:

A cascaded radar system is provided that includes a first radar system-on-a-chip (SOC) operable to perform an initial portion of signal processing for object detection on digital beat signals generated by multiple receive channels of the radar SOC, a second radar SOC operable to perform the initial portion of signal processing for object detection on digital beat signals generated by multiple receive channels in the radar SOC, and a processing unit coupled to the first radar SOC and the second radar SOC to receive results of the initial portion of signal processing from each radar SOC, the processing unit operable to perform a remaining portion of the signal processing for object detection using these results.
