Abstract

It is difficult to track the cluster target accurately because of the interaction between the clusters. In this paper, the tracking problem of cluster targets is studied. Firstly, the stochastic differential equation is used to model the cooperative motion of clusters, and the movement and measurement model of cluster target is derived. Secondly, the cluster tracking filter in the framework of Bayesian filtering is deduced, and a method of cluster partition using wavelet coefficients is proposed. Finally, in order to achieve measurement correlation in clutter environment, the JPDA target tracking algorithm is derived. The simulation results show the effectiveness of the proposed cluster target tracking algorithm in clutter environment.
基于小波系数和JPDA的可分辨聚类目标跟踪
由于集群间的相互作用,给集群目标的准确跟踪带来了困难。本文研究了集群目标的跟踪问题。首先,利用随机微分方程对集群的协同运动进行建模,推导了集群目标的运动和测量模型;其次,推导了贝叶斯滤波框架下的聚类跟踪滤波器,并提出了一种基于小波系数的聚类划分方法。最后,为了实现杂波环境下的测量相关性,推导了JPDA目标跟踪算法。仿真结果表明了该算法在杂波环境下的有效性。
