Short-Range Leakage Cancelation in FMCW Radar Transceivers

Abstract: 

Our demonstrator verifies a novel concept to mitigate unwanted close signal reflections in FMCW radar transceivers. In automotive applications, for instance, these reflections originate from the car’s own bumper, causing a severe degradation of detection sensitivity and accuracy due to the unpreventable phase noise contained in the transmit signal. We propose a concept on how to mitigate the so-called Short-Range (SR) leakage in a recently puplished paper in the IEEE Journal of Selected Topics in Signal Processing (December 2015). Therein we introduce an artificial On-Chip Target which enables almost perfect SR leakage signal estimation and cancelation with a minimum amount of chip area. It is thus the first known leakage canceler of its kind that can be realized holistically within a monolithic microwave integrated circuit (MMIC). To prove our theoretical investigations, we built a hardware prototype with discrete components, showing highly convincing measurement results.
