Abstract

The successful implementation of a linear frequency modulated continuous wave (FMCW) radar transmitter is presented, consisting of a 77-GHz voltage controlled oscillator (VCO) and a 19-GHz down-converter manufactured in a 200-GHz silicon germanium (SiGe) technology. The influence of phase noise and frequency sweep linearity on the radar system performance is briefly described, and measurement results of these parameters are compared between different architectures
