基于编队目标重心的航迹起始方法研究

Study of Track Initiation Method Based on Barycenter of Formation Target

在分析了编队目标跟踪现有的K-方法和集群引晶方法的基本原理、步骤及存在问题的此基础上,针对编队目标不同于一般多目标的特点,提出了基于编队目标重心的航迹起始方法。该算法首先根据监视区域内多目标回波的空间距离进行分群检测预处理,以形成编队目标;在完成分群检测后,再利用目标回波幅度信息求解每个编队目标的重心,以编队目标重心为等效量测实现编队目标快速、稳定的航迹起始。仿真结果证明了该方法的正确性与有效性。

Formation target tracking is a special problem compared with ordinary multi-target tracking.So,the track initiation method is proposed for formation target tracking based on barycenter,after the basic principles and steps of K-means and cluster-seeding method for group initiation are analyzed.Firstly,all echoes in the surveillance space are made sure by the divided group detection.Secondly,the barycenter of formation target is calculated by the amplitude of every target echo.At last,the equivalent echo of the formation target and its barycenter are found,and track initiation is made.Simulation shows the efficiency of track initiation method for formation target.
