静止单站纯方位目标航向估计及仿真研究

针对平面直角导航坐标系下匀速直航目标， 利用静止单站测得目标方位序 列， 基于纯方位目标运动分析(BO-TMA)理论， 采用拟线性处理方法， 对目标航向进行 递推式估计。通过多次仿真实验，研究了不同初始条件对目标航向估计性能的影响。该 方法要求简单，便于实现，所得结论为水下隐蔽单站仅利用目标方位信息快速判断敌方 运动态势及作战决策提供了参考。

Target Course Estimation Algorithm and Simulation for Stationary Single Bearing-only Observer

Aiming at the moving target with constant speed and direction in planar Cartesian coordinates, using the azimuths of arrival by stationary single observer, based on the bearing- only target motion analysis(BO- TMA)theory, pseudo-linear method is introduced here to give a recursive algorithm for the target course estimating. A large number of simulation experiments have been implemented to research the effect of diverse situation for target course estimation capability. The method has very few restrictions and is easy to be realized, it can provide some valuable assist for covert underwater observer to judge the war field situation as well as decision making quickly.
