水文条件对鱼雷声自导作用距离的影响

针对真实水文条件下鱼雷声自导对实际目标的作用距离预报问题，总结了不同海域、不同季节的典型水文条件，提出了鱼雷声自导作用距离预报方法，以射线声学理论为基础建立了传播损失预报模型，以单元散射模型为基础建立了混响级预报模型。根据声自导鱼雷的技术参数，采用网格搜索法预报真实水文条件下鱼雷声自导对实际目标的作用距离，旨在为鱼雷攻击提供建议。

Influence of Water Conditions on Torpedo Acoustic Homing Range

Aiming at forecasting the torpedo acoustic homing range for actual targets under real water conditions, this paper sum- marizes the typical water conditions in different sea spaces and seasons, presents a forecast method of torpedo acoustic homing range, and establishes a transmission loss forecast model based on the ray acoustic theory and a reverberation level forecast model based on the cell scattering model. According to the technical parameters of acoustic homing torpedo, the torpedo acoustic homing range of actual targets under real water conditions is forecasted with the grid search technique. This paper also proposes some sug- gestions for commanders to attack targets with torpedoes.
