Review-semiconductor integrated radar for sensing applications

This paper reviews recent developments of semiconductor integrated radar for modern sensing applications. It focuses on a few representative works of integrated radar sensor chips that operate in the continuous-wave mode and the ultra-wideband pulse mode. The benefits of solid state science and technology to modern radar-on-chip solution are clearly demonstrated through those examples. The paper also presents some commercial application case studies, and discusses the outlook of integrated radar solution and the corresponding need from future semiconductor technologies.
