77 GHz, FMCW radar, ACC, Offset-Loop.
This contribution describes a 77-GHz frequency modulated
continuous wave (FMCW) radar system that is completely
based on a Silicon-Germanium (SiGe) chipset. It consists
of a 77-GHz VCO, a 77-GHz receive mixer and a 19-GHz
down-converter for use in an offset-loop synthesizer. A 4×4
patch array antenna is used for the bistatic prototype system
on both the transmit and receive side. The performance of
the radar system is characterized by the standard deviation
of the range estimates acquired in statistical measurements.
