PHASE MODULATED CONTINUOUS WAVE RADAR SYSTEM THAT USES VELOCITY LABELED MULTIPLEXING FOR GENERATING

A phase modulated continuous wave (PMCW) multiple input multiple output (MIMO) radar system is described herein. The radar system is configured to compute range, velocity, and direction of arrival angle of objects relative to the radar system.

The techniques of this disclosure describe a scalable cascading automotive radar system that generates a common oscillator signal enabling consecutive chirps to be output more quickly and precisely than any previous cascading automotive radar system, thereby reducing phase noise and improving performance. The scalable cascading automotive radar system combines a respective LO signal output from at least two primary transceivers to distribute the combined signals as a common oscillator signal to be input to all the transceivers of the radar system.
