潜艇机动对鱼雷捕获概率影响的仿真研究

潜艇速度、深度与航向的变化,会引起潜艇辐射噪声声源级和目标反射强度的变化,从而将改变声自导鱼雷对潜艇的被动或主动自导作用距离.该文根据声纳方程以及鱼雷目标的能量检测模型,仿真分析了潜艇以不同速度航行时被被动自导鱼雷发现的概率、相同检测概率下不同舷角上鱼雷主动自导发现潜艇的距离及不同深度上被动自导鱼雷发现以相同速度航行的潜艇的概率.该文对研究水声对抗中潜艇的机动决策以及对研究自航式声诱饵的使用问题具有重要参考价值.

Simulation of the Effect of Submarine Evasion on Torpedo Capture Probability

The radiated noise energy from a submarine and the reflected strength to a submarine will be changed with its motion velocity,depth and course,respectively.Based on these changes,the acquisition range of passive or active homing torpedo will be changed.Based on sonar equations and detection probability model of homing torpedo,this paper simulates the possibility of passive homing torpedo finding a submarine moving at different velocities,acquisition range of an active homing torpedo finding submarine under the same detection probability and different relative bearings,the possibility of passive homing torpedo finding a submarine at the same velocity in the different depth.It is helpful for the decision of submarine evasion in the hydroacoustic warfare and the use of mobile decoys.
