基于B型灰色关联度的雷达与ESM航迹关联算法

A Track Association Algorithm of Radar and ESM Based on Type B Grey Correlation

为解决同平台雷达与电子侦察设备(ESM)的航迹关联问题,提出了一种基于B型灰色关联度的航迹关联算法。首先,对ESM数据基于灰色代数曲线模型(GAM)进行平滑处理;其次,将雷达测量数据进行坐标转换,完成雷达与ESM的时空对准;最后,计算出雷达与ESM不同航迹对之间的B型灰色关联度,并制定航迹关联的判定规则,以此选出航迹关联对。仿真结果表明,该方法效果较好,方便实现。

In order to solve the problem of the track association of radar and ESM at the same platform,this paper provides a track correlation algorithm based on type B grey correlation.First,the ESM data is smoothed based on GAM.Then,the temporal and space alignment of the radar and ESM data is achieved by coordinate transformation for the radar data.Finally,the type B grey correlation between the different track pairs of radar and ESM is figured out and the determination rules of track association are established to select,track association pairs.The simulation results show that proposed algorithm can accomplish the track association of radar and ESM effectively.
