摘　　要：随着声呐设备探测能力的大幅提升,声呐作用距离内可跟踪目标数不断增多,多目标交叉跟踪研究受到了学者们的广泛关注。传统目标方位角预测跟踪和多假设跟踪的解析过程较为复杂,交叉前手动预置跟踪对操作员要求苛刻。针对该问题,提出了一种基于过程编码的多目标交叉跟踪技术,实现水下多目标交叉状态自动判别,与现有的一些方法相比,该方法物理实现简单,跟踪稳健,交叉成功率相比交叉前手动预置跟踪提高不小于50%,适合工程应用。With the great improvement of sonar detection performance,the number of traceable targets within the range of sonar is increasing.The study of Multi-target intersecting tracking has attracted extensive attention from scholars.Traditional algorithm such as azimuth prediction or multiple hypothesis tracking is complex,and manual preset tracking before intersecting is demanding.To solve this problem,a multi-target intersecting tracking technology based on process coding is proposed to realize the automatic identification of underwater multi-target intersecting states.Compared with some existing methods,this proposed method is simple in physical implementation,stable in tracking,and has a higher intersecting success rate.It is at least 50%higher than that of the manual preset tracking before intersecting.This method is suitable for engineering applications.
