摘要
在目标跟踪过程中,当目标满足群目标条件时,多目标跟踪由于跟踪波门交叉严重,往往会误相关,因此传统的多目标跟踪方法在群目标跟踪中并不适用。为了能够有效跟踪群目标,及时获得群目标的动态信息,研究人员提出了群目标重心跟踪的思想。合并是群的一大特征,也是群跟踪过程中的一大难点。在群重心跟踪算法基础上,把合并分为点迹与航迹合并,以及航迹与航迹合并两种情况。后者采用双门限方法判断群是否可以合并,并分析了群跟踪门的构建过程。仿真验证结果表明,在群合并过程中,依然能够稳定跟踪。因此,该算法能够有效跟踪群目标,及时获取群目标的动态信息。
If the tracking-targets are group-targets,the tracking gates will intercross badly and the targets will correlate in error while the radar tracking targets,so the traditional algorithm of multiple target is not an appropriate method in the group-targets tracking.Many studiers put forward the idea of tracking the group-targets based on barycenter in order to get a better consequence and the changing information of the group.The merging is a significant character for the group-targets and a difficulty for the tracking.The paper studies the merging processfor group-targets based on group′s barycenter and the merging of group-targets includes two modes.One is merging of dots and track,the other is merging of track and track and the merging criterion of judgmennt is the method of double thresholds.The paper also analyzes the process of designing the group tracking gates.Numerous experiments verify that the algorithm can track the group-targets stably when the groups merge.So the algorithm of the paper is effective in the group-targets tracking and gets the dynamic information in time.
