摘　　要：研究了组网雷达存在系统误差情况下的航迹关联问题,采用ECEF坐标系作为公共参考坐标系,采用三门限算法进行航迹关联。将不同雷达量测的位置偏差作为粗关联门限,利用位置误差序列的样本方差建立历史航迹关联门限,最后对仍存在歧义的航迹,通过优化算法实现关联的全局最优解,与最近邻域法相比该算法可以有效实现不同目标数目与不同系统误差下的航迹关联,仿真结果显示了该算法的有效性。The problem of track association with systematic error between radar networks is researched. ECEF（Earth-centered-Earth-fixed） coordinate is taken as the common reference coordinate, and triple- threshold is used to carry out track association. The coarse threshold is set up based on the different sensors＇ measurements. The sequence of different sensors＇ measurements is taken as the history track correction threshold. Finally, the unsolved tracks are distinguished by the global optimization algorithm. The algorithm could fulfill track association for different number of targets with different systematic errors. The simulation result shows the effectiveness of the method.
