摘　　要：针对多模复合导引头在多目标航迹交叉时,采用常规航迹关联算法易出现航迹关联错误的问题,提出一种基于灰色关联度的两级实时航迹关联算法。根据航迹关联问题特点对灰色关联度计算进行修正,以航迹间的灰色关联度构成灰色关联矩阵;通过两级航迹关联判别对灰色关联矩阵进行修正,分别从航迹的整体态势相似度和航迹当前一段时间内的局部特性进行航迹关联判断,得到航迹间的最终灰色关联度;以灰色关联度最大值准则得到航迹关联对。仿真实验结果表明:在航迹交叉以及目标释放干扰使得传感器航迹数据发生错误时,该算法依旧可以正确地进行航迹关联判决。For the multi-mode composite seeker,the track correlation mistakes tend to happen using the traditional track correlation algorithms when the tracks of multiple targets cross.A novel two-stage real-time track correlation algorithm is proposed based on the gray correlation degree.A gray correlation coefficient matrix is formed by the gray correlation degree between tracks,and the calculation of gray correclation is modified according to the characteristic of track correlation.The gray correlation coefficient matrix is modified by a two-stage track correlation discrimination using the similarity of the overall motions of target tracks and the local property during the latest period of current time.Finally,the maximum criterion of gray correlation degree is exploited to obtain the track correlation pair.The simulated results show that the proposed algorithm can be used to correctly correlate the tracks when the sensors obtain wrong track data due to track crossing or target jamming.
