neighboring vertex

Firstly, group targets measurements (group measurements for short) were extracted based on the combination of the near neighbour point sets from the measurements set of individual member t.

首先,在近邻点集聚合的基础上,从传感器给出的单目标观测集合中提取出阵群目标观测(简称阵群观测);其次,按照自顶向下的方式逐次计算各个阵群观测不同子集空间分布的距离度量,并以此为基础计算阵群观测之间的关联度量;最后,通过在关联代价矩阵上应用二维分配算法得到不同时刻各个阵群观测之间的对应关系。
