摘　　要：针对现有水下作战环境中潜艇声隐蔽效能评估方法的不足,尤其是三维非均匀温盐场对潜艇声隐蔽性的影响,采用重构三维温盐场和BELLHOP3D模型,计算声场传播损失数值,结合不同艇型、海况等级和敌方声纳类型等辅助信息,利用概率论和被动声纳方程,构建指定海区不同位置处不同工况条件下潜艇的声隐蔽效能仿真模型,在输入某一海区三维温盐场数值的基础上,仿真获取该海区给定工况条件下的潜艇声隐蔽效能数值分布伪彩图。仿真结果表明,由于海水介质中温度和盐度分布不均匀,影响海区内潜艇的声隐蔽能力。潜艇在某些位置有非常好的声隐身效果,而在某些位置存在较大的暴露概率,潜艇声隐蔽效能是非均匀分布,与温度和盐度水平分布呈现弱正相关性,该方法能有效评估潜艇在不同海区和工况条件下的声隐蔽能力。该研究对于潜艇利用海洋环境达到隐蔽航行的目的以及任务海区的潜艇航路规划具有重要的理论意义和实际应用价值。In view of the shortcomings of the existing evaluation methods of submarine acoustic concealment in underwater combat environment,especially the influence of three-dimensional non-uniform temperature and salt field on submarine acoustic concealment,the acoustic field propagation loss value is calculated by reconstructing the three-dimensional temperature salt field and bellhop3d model,and combining with the auxiliary information of different types of boats,sea state grades and enemy sonar types,the probability theory and passive sonar equation are used to construct the model.The simulation model of submarine′s acoustic concealment efficiency under different working conditions at different positions in the designated sea area is established.Based on the input of the three-dimensional temperature and salt field value of a certain sea area,the pseudo color map of the submarine′s acoustic concealment efficiency value distribution under the given working conditions in the sea area is obtained by simulation.The simulation results show that due to the uneven distribution of temperature and salinity in seawater,the submarine′s acoustic concealment ability is affected.The results show that the submarine has a very good acoustic stealth effect in some locations,but there is a large exposure probability in some locations.The submarine acoustic concealment efficiency is non-uniform distribution and has a weak positive correlation with the horizontal distribution of temperature and salinity.This method can effectively evaluate the acoustic stealth ability of submarine in different sea areas and working conditions.The research has important theoretical significance and practical application value for submarine to achieve the purpose of covert navigation by using marine environment and submarine route planning in mission sea area.
