摘　　要：针对多雷达航迹加权平均融合法,分析了权值分配对融合航迹精度的影响,提出了一种权值的动态分配方法。该方法利用多雷达对相同目标跟踪的航迹信息,对各雷达输出航迹的精度进行在线估计,实现权值的动态分配,提高了融合航迹的精度。仿真实验结果验证了该算法的有效性。For the weighted average method used in multi-radar track fusion,the influcncc of weighting factor allocation on the accuracy of the fused track was analyzed, and an algorithm of woighting factor dynamic allocation was presented. The output track accuracy of each radar was estimated online by exploiting the same target＇s track informationa coming from multi- radar system. The dynamic allocation of the weighting factors was realized and the accuracy of the fused track was improved. The results of the simulation experiment show that this algorithm is really effective.
