摘　　要：为解决分布式跟踪系统中的航迹相关问题,提出了一种基于综合相似度的航迹相关方法。该方法先根据传感器测量误差确定航迹相关的粗相关门限,再构造航迹状态相似度、航迹参照拓扑相似度和相关拓扑矩阵,形成航迹综合相似度,最后通过解算综合相似度相关矩阵实现航迹相关。蒙特卡罗仿真结果表明,该方法在传感器有一定的系统误差以及目标密集条件下可有效实现航迹相关,具有工程应用参考价值。To solve the track correlation problem in a distributed target tracking system, a track correlation is presented based on comprehensive similarity. Firstly, the coarse threshold is calcu- lated with the sensor measurement errors. Then, the track status similarity, the track reference topology similarity and the related topology matrixes are constructed for forming track integrated similarity. Finally, the track correlation is implemented by calculating integrated similarity matri- xes. Monte Carlo simulation results show that the method can realize the track correlation under the conditions of existing system errors and dense targets, thus it has a certain value in engineer- ing application.
