本文是关于多站多目标跟踪技术的一篇综述性文章,文中列举了多站跟踪系统的优越性和存在的问题,着重说明其中困难问题之一:在稠密目标和杂波环境下,各站目标点迹或航迹之间的相关问题。文中介绍了现有的几种算法,同时指出算法的优化必需按实际情况有针对性地进行,企图寻求一个通用的而又能实现的最优算法将是非常困难甚至是徒劳的。 This article is a review article about multi-station multi-target tracking technology. The article lists the superiority and existing problems of multi-station tracking system, and focuses on one of the difficult problems: in the dense target and clutter environment, each station Related issues between target spot or track. In this paper, several existing algorithms are introduced. At the same time, it is pointed out that the optimization of the algorithm must be targeted according to the actual situation. It is very difficult or even futile to seek a universal optimal algorithm which can be implemented.
