摘要
针对"当前"统计模型算法中加速度极限值预先设定对算法造成的不利影响,提出了一种改进的机动目标跟踪算法,即位置偏差估计自适应算法.该算法利用位置预测估计与位置估计之间的偏差对噪声方差进行自适应调整,从而避免了加速度极限值的预先设定问题,提高了机动目标的跟踪性能.仿真结果也表明了该算法的良好跟踪性能.
An improved algorithm of maneuvering target track is presented because there is adverse influence of limit acceleration presupposed in the aspect of target track. The improved algorithm is called position deviation estimation algorithm. The deviation between the position forecast estimation and the realtime position is used for adaptive adjustment to avoid the problem of presupposing the limit acceleration and improve the capacity of maneuvering target track. The simulation result shows that the algorithm has good efficiency of maneuvering target track.
