Abstract
High resolution radar imaging is highly desired for autonomous vehicle systems but the complexity and cost have been prohibitively expensive. Coded Aperture Radar (CAR) is a technique that simplifies the RF hardware, utilizing single-bit phase shifters to obtain angular information, and enables digital beamforming with only a single transceiver. This paper describes the development and measured results of a CAR sensor developed for 77 GHz operation that utilizes 128 array elements to digitally synthesize directional beams. The authors quantify the sensor performance in cluttered environments.
