摘　　要：针对分布式多传感器信息融合系统中航迹关联运算量大的问题,提出了一种分区快速航迹关联算法。该算法将目标区域划分成若干目标子区域,为了消除传感器测量误差对航迹关联的影响,相邻目标子区域之间设置重叠区域,并给出了重叠区域宽度计算公式。只对落在每个目标子区域内的航迹进行关联,不同目标子区域之间的航迹不进行关联,并通过算法复杂度分析给出了最优分区数的判定方法。仿真实验表明,该算法可有效降低航迹关联运算量,适合于工程应用。For the problem of large computational cost of track association in multi-sensor information fusion system, this paper proposes a fast zoned track association algorithm.This algorithm splits the target area into a number of target sub-areas.In order to eliminate the influence of sensor error on track association, the overlapping area is set among adjacent target sub-areas, and the calculation formula of overlapping area width is given.Association decision will be performed only for the track points in the same target sub-area, but not in different target sub-areas.We got the way to decide the optimal zoned number by analyzing the algorithm complexity.Simulation experiments show that the algorithm can effectively reduce the calculation amount of track association, which is suitable for engineering application.
