一种多阵联合的拖线阵左右舷分辨方法

A port-starboard discrimination method of towed array based on multi-arrays joint

左右舷模糊一直是困扰拖曳线列阵声呐使用的关键技术,其制约了拖线阵声呐的使用效能。现有声呐系统装备的首端阵和舷侧阵均具有左右舷分辨能力,其与拖线阵声呐的信息互补性为拖线阵左右舷分辨提供了可能。文中提出一种多阵联合的拖线阵左右舷分辨方法,即利用舷侧阵和拖线阵公共频段的联合波束形成技术实现拖线阵的左右舷分辨,通过仿真分析验证了所提方法的有效性。结果表明,所提方法能够实现拖线阵左右舷分辨,平均分辨正确率不低于90%。

The port-starboard fuzzy is always the key technique that confuses the use of the towed array sonar.The using efficiency of the towed sonar in combats is restricted.The bow-mounted array sonar and the flank array sonar of the existing sonar system equipment have the ability to distinguish between the left starboard and the right starboard,and the information complementation with the towed array sonar provides the possibility for the towed sonar port-starboard discrimination.In this paper,a port-starboard discrimination method of towed array based on multi-arrays joint is proposed,that is,the joint beamforming technology of the shared frequency band between the flank array sonar and the towed array sonar is used to distinguish the ports.The effectiveness of the proposed method is verified by the simulation analysis.Results show that,port-starboard discrimination of towed array is realized using the proposed method,the average resolution accuracy is no less than 90%.
