Fast chirp FMCW radar in automotive applications

FMCW (frequency-modulated continuous wave radar) modulations have been popularly implemented in the automotive radar applications. This document demonstrates system requirement for a new FMCW modulation - fast chirp modulation. It largely improves the range resolution compare to general automotive FMCW Radar system. A practical RF-front end system is also presented at the end of the paper.
