协同侦察系统增加猝发探测功能的定位技术

协同侦察系统增加猝发式有源探测功能，使系统既具隐蔽性又可精确定位，是一个值得研究的问题。分析对远距离目标的多平台协同侦察定位和单站猝发式有源定位的定位误差分布特点，提出了协同侦察增加猝发式有源探测的综合探测体制，描述了系统工作流程，给出了协同侦察增加猝发探测的最大似然定位算法，仿真分析了定位性能。仿真结果表明，多平台协同侦察系统有较高的切向定位精度，猝发式有源定位有较高的径向定位精度，综合定位能将二者定位性能进行优势互补，一定程度上提高定位精度。

Location technology of synergy reconnaissance system adding instantaneous detection function

Synergy reconnaissance system adding instantaneous active detection function ,which make the system more concealed as well as achieve accurate algorithm ,is apparently worthy of studying .The error dis‐tribution features of multi‐platform synergy reconnaissance location and single‐station instantaneous active location for remote target are analyzed in the issue .Then the comprehensive detection system of synergy re‐connaissance adding instantaneous active detection is proposed , and the work procedure of the system is described .In the end ,the maximum likelihood estimation location algorithm of the system is deduced as well as the location performance is analyzed by simulation .With simulation approach proposed ,the multi‐platform synergy reconnaissance systemhave good crosswise location accuracy ,and the instantaneous active location have good lengthways location accuracy .So comprehensive location can make both of them complemented and improve the location performance .
