Range detection is an challenging task, especially if high accuracy has to be reached. The hereby proposed 61 GHz continuous wave radar system is based on a phase detector using Six-Port technique. For accuracy enhancement an improved isolation radar coupler has been introduced for broadband frequency modulated continuous wave radar as well as narrow band radar techniques. Furthermore, a Six-Port network based on four hybrid couplers is presented. Finally, the most important system sub-components have been validated by measurements.
