Abstract :
The influence of phase noise and frequency sweep linearity on radar system performance is discussed using measurement data of a linear frequency modulated continuous wave (LFMCW) radar transmitter, consisting of a 77-GHz voltage controlled oscillator (VCO) and a 19-GHz down-converter manufactured in a 200-GHz silicon germanium (SiGe) technology.
