| Abstract: | The technical background, status and challenges of silicon-based 77 GHz transceiver for automotive radar were reviewed. Firstly, the assignments of the spectrum, the selections of semiconductor process and radar architecture for millimeter wave vehicle radar were introduced. On this basis, the technological evolution of the automotive radar transceiver chips for the past decade was summarized and its development trends were analyzed. The 77 GHz radar transceiver as well as the latest corresponding millimeter wave integrated circuit technology in SiGe and CMOS process were discussed respectively. Finally, the challenges for designing the millimeter wave automotive radar transceivers were proposed through further analysis. |
