Design of a mmWave MIMO Radar

This article presents a 60GHz frequency modulated continuous wave (FMCW), frequency-division multiplexing (FDM), multiple-in-multiple-out (MIMO) radar system for commercial radar applications. The unique architecture enables the total number of transmit (Tx) and receive (Rx) channels to be scaled by the number of ICs in the system, while still maintaining phase coherence between channels. The approach provides high frame-rate measurement, excellent phase stability and a large field of view (FoV). The radar architecture and ICs are designed so the system can be scaled to much larger radars.
