| 摘 要： | 航迹关联对航迹融合结果具有决定性影响。为了解决组网雷达存在系统误差情况下的航迹关联问题,以不同雷达的量测位置偏差建立粗关联门限进行航迹粗关联。对仍存在歧义的航迹,运用最小二乘法进行数据拟合,得到量测序列的对应系数,建立局部关联门限,仿真结果显示了该算法的有效性。

| Abstract: | Track association is crucial to the result of track fusion.The problem of track association when there is systematic error in the radar network was studied,and coarse track association was set up based on the measured positional deviation of different radars.Least square algorithm was adopted to get the corresponding modulus of the left tracks,and the local association threshold was set up with the corresponding modulus.Simulation result shows the effectiveness of the methods. |

| Keywords: | track association systematic error least square algorithm data fitting |
