水下运动目标浅海低频矢量干涉谱研究
Research on Low-Frequency Vector Interference Spectra of Underwater Moving Targets in Shallow Water
摘要
Abstract
The analysis of radiated noise from underwater moving targets has always been a hot topic in underwater attack and defense.In the context of gradually decreasing noise levels,scholars have turned their attention to low-frequency vector sound fields in order to obtain more sound field information.In this article,the formation mechanism of shallow water vector acoustic interference structures is studied.The radiated noise of underwater moving targets is modeled using a three-parameter model method,and the trajectory equation of interference fringes is derived.The effects of CPA(closest point of approach)distance,receiver depth,seabed parameters and sound velocity gradient on the structure characteristics and intensity of vector sound field interference fringes are systematically analyzed.Finally,the interference phenomenon of vector sound fields is analyzed and verified using the measured hydrological data.The results show that the vector sound fields contain unique interference information,and the deep mining of their formation rules and characteristics can provide a new theoretical basis for low-frequency shallow water target detection and sound field characteristic analysis.关键词
