摘要
无源定位通过接收目标的有意、无意辐射或反射信号来实现定位,定位系统不向外界发射电磁波信号,具有隐蔽性好、作用距离长、生存能力强等特点,在民用和国防领域均具有广泛的应用。本文从无源定位内涵与特点、在军民领域的典型应用、关键性能指标、无源定位关键技术以及基于外辐射源照射的无源定位五个方面探讨了国内外研究现状和技术特点,并展望了无源定位技术的未来发展趋势。
Passive localization is realized by receiving the intended and unintended radiation,or reflection signals from the target.The locating system doesn’t emit electromagnetic signals to the outside,so it has the characteristics of good concealment,long operating distance and strong survivability,which has been widely used in civil and national defense fields.In this paper,the connotation and characteristics of passive localization,typical applications in military and civil fields,key performance indicators,key technologies of passive localization and passive localization based on external radiation sources are discussed,and the future development trend of passive localization technology is prospected.
