杂波环境中多机动目标自适应跟踪算法

An Adaptive Tracking Algorithm for Multiple Maneuvering Targets in Clutter Environment

针对多杂波多机动目标环境引起的跟踪误差和实时性问题,提出了一种结合IMMPDA和改进的IMMJPDA的自适应多机动目标跟踪算法,在跟踪过程中根据目标之间的距离来选择IMMPDA和改进的IMMJPDA算法中的一种跟踪方法,其中改进的IMMJPDA算法是根据每个模型产生的关联矩阵取并集产生关联矩阵。自适应多机动目标跟踪算法能在有效地提高跟踪实时性的同时,减小目标机动时位置误差的超调。通过蒙特卡罗仿真表明,算法是有效的。

In view of the tracking error and real - time problem caused by the multiple maneuvering target tracking in clutter environment, an adaptive maneuvering multi -target tracking algorithm based on the IMMPDA and modified IMMJPDA is proposed. The distance of targets decides which tracking method between IMMPDA and modified IMMJPDA would be used for tracking. The adaptive maneuvering multi - targets tracking algorithm combines all association matrixes which are generated by all targets＇ models. This new algorithm can improve the real - time capability and reduce the overshoot of error in position. The validity of this algorithm is illustrated through Monte - Carlo simulations.
