Integrated Stretch Processed S-Band Digital Radar System

A stretch processed radar system is presented in this paper. The radar system operates at S-band and employs stretch processing. Stretch processing helps a radar system to process wideband signals to increase its resolution, while relaxing its analog-to-digital converter's sampling rate requirement. The reported radar system exhibits a high dynamic range which enables it to be used in variety of applications such as surveillance systems. Furthermore, the radar system architecture comprises of multiple receiver channels which enable the radar to detect objects of interests at certain angular locations and reject jammers. The digital radar testbed was built using microwave components. Moreover, the radar system is integrated on a single die chip using IBM 180 nm CMOS process with a low power consumption, small form factor, and high performance.
