摘　　要：雷达跟踪密集编队目标时容易出现频繁起批的问题,在获得编队整体合批航迹的需求背景下,提出一种基于滑窗式航迹关联的编队目标识别算法。该算法首先给出基于加权航迹关联判决的两航迹编队识别模型;然后进一步采用循环阈值判断完成多航迹的编队分割;最后进行滑窗多时刻的编队识别确认与合批处理,得到编队合批航迹。仿真结果表明,算法在编队平行机动和交叉运动环境下频繁起批时,均能够有效识别编队目标并生成合批航迹。Frequent track initiation often happen when radar tracks dense formation targets.Due to the need of merging formation members＇ tracks,a formation target recognition algorithm based on sliding window track association is proposed.A two-track formation recognition model based on weighted track association decision is given firstly.Then,circulated threshold decision is used for multiple tracks＇ formation separation.At last,sliding window of multi-time formation recognition confirming and formation merging are undertaken to generate the merging track.Simulation results show that： the algorithm can recognize formation target and generate merging track whether the formation is maneuvering in parallel or is making crossing moving in which frequent track initiation happens.
