摘　　要：联合概率数据互联是由概率数据互联发展而来,应用于密集杂波环境下密集多目标跟踪的一种关联方法。它对聚内所有的目标和量测进行全局的考虑,计算在联合事件条件下的关联概率。文中概括了JPDA基本理论,指出了计算关联概率时可行事件搜索方法和为减少计算量采用的各种简化算法,最后总结了实际工程应用中的JPDA目标跟踪方法。JPDA is extended from PDA and has been applied as a way of association of closed multi-target in dense clutters environment.It takes into account all targets and measures in the cluster and calculates the association probability conditioned on joint events.The basic theory of JPDA and the calculation of association probability were summarized.The ways of searching feasible events used to calculate the association probability were displayed.To reduce computer loading,the simplified methods were introduced.Fi...
