针对仅能观测目标一维信息的多基地雷达系统,提出了一种基于局部航迹关联的多目标跟踪快速算法.该算法通过各接收机的局部跟踪处理,在获得目标一维航迹的基础上,利用目标的速度信息、局部航迹的冗余性及其与目标的一一对应关系,分级剔除了由于组合定位产生的大量虚假目标,进而通过局部航迹的关联提高了多目标跟踪的稳定性.与传统的集中式跟踪算法相比,该算法避免在融合中心进行复杂的"量测-量测"与"量测-航迹"关联运算,显著提高了计算效率,具有较好的实时性,易于工程实现.

A fast algorithm for multi-target tracking based on local track association was presented for multi-static radar that could only one-dimensional information of targets. On the basis of the one-dimensional track of a target provided by local tracking treatments of the receiver, this algorithm could utilize the velocities of targets, redundancy of local tracks and one-to-one correspondence of target-to-local track to eliminate false targets introduced by combined localization. Then stable multi-target tracking could be achived by local track associating. Compared with traditional centralized tracking algorithms, this algorithm avoids complicated measurement-to-measurement and measurement-to-track association in the fusion center thus remarkably improving calculation effectiveness. The algorithm is easy to implement in engineering with real-time performance.
