Study on Detection Scope of Bistatic Airborne Sonobuoy under Typical Hydrological Environment

摘要:

航空声纳浮标多基地探测是应对水下目标声隐身能力持续提高的有效技术途径之一。分析了航空声纳浮标的指标,给出了双基地声纳配置,采用双基地声纳方程为依据,利用数值仿真的方法计算了三种典型海洋环境条件下双基地声纳浮标探测范围,讨论了海洋环境对多基地声纳探测的影响,为航空声纳浮标多基地战术使用奠定技术基础。

Abstract:

Multistatic airborne sonobuoys is one of the effective technical approaches to deal with the continuous improvement of acoustic stealth ability of underwater targets. The index of airborne sonar buoy was analyzed, and the configuration of bistatic sonar was given. Based on the bistatic sonar equation, the detection range of bistatic sonobuoy under three typical marine environmental conditions was calculated by numerical simulation. The influence of marine environment on multistatice sonar detection is discussed, which lays a technical foundation for the multistatic tactical operation of airborne sonobuoy.
