基于局部航迹关联的多基地雷达多目标跟踪快速算法

A fast multi-target tracking algorithm based on local track association for multi-static radar

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 muhi-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 onedimensional 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.
