摘要
给出了一种最小方差意义下的最优航迹滤波方法。该方法能根据雷达与红外探测设备所测得的异步测量信息进行实时滤波,无需将测量数据进行同步对齐,避免了现有算法的不足,更便于工程应用。数字仿真结果证明,该方法能提高航路估计精度。
In this paper an optimal filtering in minimum mean square error (MMSE) sense is given, which can process realtimely measurements from radar and infrared detector with no need for radar and infrared detector working synchronously,and it is much easier to be applied in engineering.Computer simulation results show that the proposed algorithm is feasible and effective to improve the estimated course accuracy.
