Passive radar is a new type of bistatic / multistatic radar that uses signals emitted by non-cooperative illuminators and only passively receives scattering signals for target detection. Its key feature is independence from cooperative illuminators and therefore does not need to apply for dedicated frequencies, which is a significant advantage in modern society where spectrum resources are becoming increasingly scarce.

Compared to active radar, passive radar offers more flexible deployment, lower networked detection costs, superior low-altitude coverage, and robust detection of slow-moving small targets. Therefore, it has attracted great attention in academia in recent years. This report covers passive radar's basic principles, the current domestic and international development status, and the key technologies. It highlights Wuhan University's research on low-frequency multi-illuminator passive radar networks  supported by national key projects. The report also outlines future development directions and application prospects of this technology.


Xianrong Wan received the B.E. degree in electrical and electronic engineering from the former Wuhan Technical University of Surveying and Mapping, Wuhan, China, in 1997, and the Ph.D. degree in radio physics from Wuhan University, Wuhan, China, in 2005.

He is currently a Professor and the Ph.D. candidate supervisor with the School of Electronic Information, Wuhan University, Wuhan, China. He hosted and participated in more than ten national research projects and published more than 130 academic papers. His main research interests include design of new radar systems such as passive radars and over-the-horizon radars, and array signal processing.
