Intelligent transport systems (ITS) is a new field of electronics for the coming century. Automotive radar is one of the biggest challenges among them. The frequency allocated for automotive radar is 76 GHz in US, Europe, and Japan. Due to the short wavelength of the radar, several difficulties arise for commercial use. Technologies for cost reduction are required even for the high-frequency applications. A circuit design method for low cost 76 GHz radar chipsets is described here.
