基于速率先验信息的固定单站仅测角目标运动分析

Target moving analysis based on speed prior information by a fixed single observer using bearing⁃only measurements

针对固定单站无源定位中仅利用角度对匀速运动目标定位跟踪问题,将速率信息视为先验约束,研究并提出基于伪线性估计和加权伪线性估计的目标运动分析算法。仿真实验表明,固定单站无源定位系统在速率先验信息条件下可以通过仅测角实现对匀速运动目标的定位跟踪。

Considering the problem of locating and tracking constant velocity targets only from angles in the passive location of fixed single observer,the speed information is regarded as a prior constraint,and a target motion analysis(TMA)algorithm based on pseudo-linear estimation(PLE)and weight pseudo-linear estimation(WPLE)is proposed.Computer simulation shows that the fixed single observer passive positioning system can track constant velocity target by measuring angle only under the condition of speed prior information.
