摘要
随着电子干扰与反辐射等雷达对抗系列技术的快速发展,有源定位技术以雷达为代表遭受日益严重的威胁。在自身不辐射的条件下无源定位跟踪系统可以被动地接收辐射源的电磁波信号,经过对其各项参数的测量,可以确定隐蔽地辐射源的运动状态及位置,在电子战情景下对于提高系统性能具有十分重要的作用。按照观测站的个数对无源定位跟踪系统进行分类可分为两大类:多站无源定位和单站无源定位。笔者分别阐述了多个观测站和单个观测站无源定位分类、系统特点及定位算法,剖析各种定位算法并对各种定位法进行误差的评估。
With the rapid development of radar countermeasures such as electronic jammers and anti-radiation missiles,the active position such as radar is threatened strongly.The passive positioning system gives no radiation wave itself but receives passively the electromagnetic signals radiated from other source and pin points its location as well as its moving state by measuring the parameters,this feature of staying in concealment provides a fantastic improvement in its survival ability under E-war environment.Single station location and multiple station location are the two kinds of the passive positioning system which is divided by the number of the observatory.The classification,system characteristics and localization algorithms of passive location of single station and multiple stations are described in this paper.
