中文摘要：

针对同平台纯方位多传感器的航迹相关问题，提出了基于B型灰色关联度的纯方位航迹关联算法．该算法将每条航迹的方位数据看作是时间的离散函数，不同传感器的航迹经过时间对准后，形成了具有相同时标的目标方位信息序列，通过对多传感器目标航迹的方位信息进行灰色关联分析，计算出各航迹对的B型灰色关联度，形成B型航迹灰色关联度矩阵，计算λ-截航迹灰色关联矩阵，并根据该矩阵确定航迹关联对．仿真试验结果表明，该方法能有效地实现同平台纯方位多传感器的航迹相关．

英文摘要：

For the track correlation problem of bearings-only multi-sensor on the same platform, this paper presents a bearing-only track correlation algorithm based on the B-mode grey correlation degree of grey system theory. In this algorithm, each track＇s azimuth information is considered as a discrete function of time, the grey correlation analysis for multi target track＇s azimuth information is performed by using the B-mode correlation degree, the matrix of track grey correlation degree of the B-mode is calculated and the track correlation pairs are determined. The results of simulation experiment show that this algorithm can effectively accomplish track correlation for the bearings-only multi-sensor on the same platform.
