潜艇隐蔽性建模与仿真研究

Modeling and simulation for submarine concealment capability

隐蔽性是潜艇生存能力的重要保障,受到诸多因素的制约,除了潜艇本身的隐身性能和敌方的探测系统性能之外,海洋环境对潜艇的隐蔽性也有相当大的影响。本文给出了海洋水文要素与声速的关系,在分析了相关海域的水文条件基础上,基于声线理论和声呐方程,建立了被动声呐对潜探测的数学模型。针对不同的声速剖面,进行了仿真实验,并对结果进行了详细的研究,所得成果为潜艇隐蔽性研究提供了理论依据,也为潜艇的顶层设计和研究工作提供参考。

The concealment capability of submarine is an important guarantee for submarine viability. It is restricted by a good many factors such as the concealment capability of submarine, the detecting ability of enemy, the sea environment and so on. The relation between hydrographic elements feature and velocity of sound in sea was analyzed. Based on the acoustic ray theory and the sonar equation, the mathematics models for passive sonar detecting submarine were established. According to various velocity of sound section,several simulation experiments were researched. The simulation result provides the theory foundation for the research of submarine concealment capability, which also affords the reference for submarine superior design.
