An E-band Phase-Modulated Bistatic Radar with 10mW/Channel Fast-Time Baseband Processing

This work presents a bi-static phase-modulated pulse radar based on analog processing of the fast-time radar signal compatible with communication systems. Based on the proposed scheme we implement an SoC with four parallel processing units consuming 10mW/channel with the quadrature receiver enabling phase-insensitive detection of multiple targets. The 60GHz radar chip is fabricated in 65nm TSMC with a total area of 1.6mm2. We calibrate and characterize the radar in both monostatic and full bistatic modes. The system demonstrates −90dBm multi-target detection sensitivity and a 7.3cm rms range precision across the full measurement range. This work features the first bi-static E-band module featuring analog fast time processing for energy efficient and scalable radar sensing.
