Abstract
本发明公开了一种基于多维特征融合的航迹匹配方法及系统，其包括：获取目标飞行器的点航迹数据，并剔除其中的异常值得到正常点航迹数据；提取出正常点航迹数据的多维特征，并对其标准化处理得到标准化多维特征；确定目标飞行器在航迹场景中的场景复杂度，并基于其和权重分配算法动态确定标准化多维特征的权重；基于标准化多维特征及权重进行特征融合计算得到待匹配点航迹的融合相似度，并基于其判断点与航迹是否匹配；在判断待匹配点航迹无法匹配后，对标准化多维特征的权重进行更新调整。本发明能够利用多维航迹特征、适配异构数据和动态调整特征权重，提高了航迹匹配准确度，可以满足高实时性场景的需求，且适用于长期监测运行。
