摘　　要：为了解决组网雷达存在系统偏差情况下的航迹关联问题,提出了基于拓扑序列法的灰色航迹关联方法。首先,采用灰色理论生成当前时刻目标拓扑序列的灰色关联矩阵,并建立航迹间的相关度量;然后,运用全局最优化方法对相关度量矩阵进行最优化分配获得航迹关联对。该算法采用全局最优化方法避免了门限选择不当对正确关联概率带来的影响,有效地利用了航迹的空间分布信息和状态信息。仿真结果表明,该算法可以有效地实现系统偏差情况下的航迹关联。To improve the track association with sensor bias between networking radars, a novel gray track correlation algorithm based on topology sequence method is proposed.Firstly, the gray theory is utilized to get the gray correlation matrix of topology sequence, and the correlation measurement between tracks is set up.Then, the correlation measurement matrix is processed by global optimization method to get the association couples.The algorithm makes use of global optimization to avoid the influence on correct probability owing to the improper choice of threshold, and utilizes space distribution and status messages of the tracks effectively.The simulation results show that the track correlation with sensor bias can be achieved more effectively.
