由于存在传感器丢失目标观测值的情况,将造成拓扑序列法等高性能航迹相关算法失效。文中提出了区域匹配算法,以区域内所有目标的最大匹配支持度为基础,从整体上优化航迹的对应关系。算法考虑了存在误差的情况下,不同雷达所形成目标观测值的偏差最大值,把绝对距离作为匹配航迹的约束条件,大大减少了匹配的计算量。文中以目标丢失率为条件,仿真了误匹配率和正确匹配率性能指标,它们都具有较好的鲁棒性。

High performance track correlation algorithms such as topology sequence method will fail when detection sensor loses target measurements. The area matching algorithm was introduced based on maximum matching support measure and correspondence relation of all targets was optimized. Since the positions of sensor report targets will not differ too much even affected by sensor detection errors, targets in-between distance were adopted as optimization constraint condition to greatly reduce calculation burden. The error match ratio and successful match ratio were simulated under changing target lost ratio for area matching algorithm, which showed good robustness.
