摘要
临近空间目标飞行器的高速、高机动特性给地面防御系统对其定位和跟踪带来了巨大的困难,传统的滤波算法无法给出精确的目标状态估计,跟踪性能变差。为了更好地满足机动式弹道滤波的需要,通过双站红外跟踪方法与卡尔曼滤波算法相结合,实现对临近空间目标飞行器跟踪,并保证了定位跟踪精度在允许范围之内,Matlab仿真结果验证了算法的有效性。
The characteristics of high speed and high maneuver for near space target vehicles have brought great difficulties with ground defense system for maneuvering target localization and tracking. Tra- ditional filtering algorithms obviously cannot give accurate target state estimation and the tracking perform- ance has declined. In order to better meet the needs of mobile trajectory filtering, the way of comb Kalman filtering algorithm and near space target vehicle. This bi-station algorithm used for localization and tracki ining ng of guarantees that the accuracy of localization and tracking for target is within the allowable range. The validity of the algorithm is verified with Matlab simulation results.
