摘要: 在分布式数据融合系统中,局部探测航迹在融合中心进行航迹关联后,需分配综合批号以确定局部航迹与系统航迹的对应关系,以便后续的融合处理。实际应用中,因关联错误的存在,可能导致后续自动编批算法的失效,进而造成系统航迹断续等故障。提出了一种基于渴望度的关联航迹自动编批算法,在航迹关联与航迹融合之间,根据渴望度为局部航迹分配综合批号,以实现关联航迹与系统航迹的对应。在真实反映关联关系的前提下,还可确保在有限关联错误下系统航迹批号的稳定性,使某一批号在不同时间尽可能地代表同一目标。所提出的算法已在实际的工程系统中得到应用,具有较好的稳健性。

Abstract: In the distributed data fusion architecture, the general batches should be organized to make local tracks be correspondent with systemic tracks, after local tracks are associated in fusion center. Thus, following tracks' fusion can be dealt conveniently. In the practical engineering systems, the association mistakes can make the following automatic algorithm for organizing batches invalid, and cause systemic tracks intermittent and fail to work. An automatic algorithm for organizing batches of associated local tracks was proposed. In this algorithm, the local tracks would be distributed with general batches according to the desired degree between association of tracks and fusion of tracks. It could make the association tracks be correspondent with the systemic tracks. Besides reflecting real associated relationship, the proposed algorithm also guaranteed the stability of fused tracks batches and made the batch represent the same object in different time. The proposed algorithm has been applied into the practical engineering system, and it has good stability.
