无源探测雷达系统的现状及发展趋势浅述

摘要

The passive detecting radar system on external illuminator has many advantages such as good invisibility,anti-stealth,anti-jamming capability,and it is simple and reliable.now it has became the hot points of research.The current researching status and general developing situation of passive radar system are introduced,the performance of an passive coherent detectlon and tracking radar system based on FM broadcasting is analyzed,and the further development of this kind radar are discussed in this paper.%基于外辐射源的无源探测雷达系统具有隐蔽性好,反隐身能力及抗干扰能力强、系统简单可靠等优点,目前已成为各国研究的热点.文章介绍了无源探测雷达系统的发展概况和研究现状,给出了一种基于FM调频广播信号的无源探测和跟踪系统的性能分析,并对该类雷达技术的未来发展趋势做了有益的探讨.
