A 79GHz 2×2 MIMO PMCW radar SoC in 28nm CMOS

This paper describes a 28nm fully integrated 79 GHz Phase Modulated radar SoC including 2TX, 2RX and the mm-wave frequency generation. A custom digital core generates the pseudo random sequence and performs correlation and accumulation of the digitized received data. With 1W power consumption, 7.5 cm range resolution is achieved while antennas arrangement allows for 5° resolution over ±60° elevation and azimuth scan in 2×2 code domain MIMO operation.
