- 针对现有潜艇隐蔽效能模型评估方法单一、计算效率低等问题，构建了基于海洋环境数据与潜艇工况的潜艇隐蔽效能模型，用于潜艇隐蔽性的评估，同时提出一种基于层次细节算法的快速计算方法，用于潜艇隐蔽效能快速计算。首先，通过海洋温盐场计算海洋声速场，利用射线Bellhop模型计算声传播损失值；其次，分析潜艇工况与运动规律和被动声呐投放深度对探测能力的影响，结合概率论和被动声呐方程构建潜艇隐蔽效能模型；然后，利用误差反向传播算法建立BellhopBP模型，采用层次细节算法思想，实现隐蔽效能快速准确的计算。最后，在不同大小和位置的海域进行隐蔽效能仿真实验。实验结果表明，该潜艇隐蔽效能模型和快速计算方法可以快速准确地计算潜艇隐蔽效能，计算效率约提高至现有方法的12～25倍。该研究为潜艇隐蔽航行的航迹规划研究提供参考。
Aiming at the problems of single evaluation method and low calculation efficiency of the existing submarine concealment effectiveness model, a submarine concealment effectiveness model based on marine environment data and submarine working conditions is constructed. Rapid calculation method for rapid calculation of submarine concealment effectiveness. Firstly, the oceanic sound velocity field is calculated by the ocean temperature and salt field, and the sound propagation loss value is calculated by using the ray Bellhop model; secondly, the influence of the submarine operating conditions and motion laws and the depth of passive sonar deployment on the detection ability is analyzed. Combined with probability theory and passive sonar equations, the Submarine concealment effectiveness model; then, the BellhopBP model is established by using the error back propagation algorithm, and the level of detail algorithm idea is used to achieve fast and accurate calculation of concealment effectiveness; finally, concealment effectiveness is simulated in sea areas of different sizes and locations. experiment. The experimental results show that the submarine concealment effectiveness model and fast calculation method can quickly and accurately calculate the submarine concealment effectiveness, and the calculation efficiency is increased to 12～25 times that of the existing methods. This research provides a reference for the track planning research of submarine covert navigation.
