Abstract
The DC-offset compensation of a monostatic FMCW-radar transceiver using transmission line (TL) length optimization is proposed. This approach can be implemented on a 77 GHz SiGe MMIC (Monolithic Microwave Integrated Circuit) with no extra costs and does not degrade the sensitivity for immediate targets needed for the stop-and- go functionality of modern ACC (Adaptive Cruise Control) systems. The theory of the DC-offset generation will be discussed and a network analysis of the transceiver will be presented. It is shown that the compensation is possible over a wide range of circuit imperfection values.Keywords
