弹道滤波算法研究

The Filter Algorithms of Ballistic Target

为导引我方发射的制导炮弹等目标,需要在炮瞄雷达跟踪炮弹的基础上准确估计炮弹目标的位置、速度等状态信息。鉴于直接对测量的弹道轨迹建立常规运动模型滤波效果较差,提出了两种方法。一种基于弹道偏差滤波的方法,另一种是基于弹道方程滤波方法。仿真计算比较结果表明文中建立的弹道滤波算法对弹道类目标的滤波精度和反应时间上有大幅度提高。

To control and guide a cannonball or missile, the state （position and velocity） of the guide cannonball or missile should be estimated by the track data of fire control radar. The two new filter algorithms of ballistic target are proposed in this paper to replace the general ballistic filter. One is the ballistic deviation filter; another is the filter base on the differential equation of the ballistic. The simulation and comparison shows that the precision and reaction time of new filter algorithms of ballistic target have been improved greatly.
