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。
Aiming at the uniform direct target under the plane right-angle navigation coordinate system, the target azimuth sequence is measured by stationary single station. Based on the pure azimuth target motion analysis (BO-TMA) theory, the target direction is recursively estimated by the quasi-linear method. Through several simulation experiments, the influence of different initial conditions on the performance of the target heading is studied. The method is simple and easy to implement, and the conclusion provides a reference for the submarine submarine single station to quickly judge the enemy’s movement situation and combat decision-making using only the target bearing information.
