摘　　要：针对分布式雷达网中多航迹关联时间复杂度高的问题,提出了一种分布式多雷达区域航迹关联方法。在定义了方格坐标系的基础上,根据一定的划分准则,将整个目标区域分剖成若干子区域。在相邻子区域内进行关联性判断,而非相邻子区域内不进行关联性判断。通过典型的场景计算验证了该方法的可行性和有效性。To solve the high time complexity problem of multi-track correlation in distributed radar network,a method of distributed multi-radar regional track correlation is proposed.Firstly,the square grid coordinate system is defined and the entire target region is partitioned to several sub-regions according to a certain division rule.Then,the correlation judgment of tracks in adjacent sub-regions is carried out while the correlation judgment of tracks in nonadjacent sub-regions is not carried out.Finally,the feasibility and the validity of the regional track correlation method are validated based on a typical test scenario.
