针对水下航行体执行特定任务时易被敌高空遥感探测器发现的问题,对其兴波尾迹探测概率进行分析。在分析兴波尾迹形成机理的基础上,根据势流理论,运用格林函数对流体的点源问题进行分析,建立水下航行体的兴波尾迹模型;根据海面波浪模型和能量等分法,模拟随机海面提取信噪比,构建水下航行体被高空遥感探测器发现时的暴露概率模型,仿真不同海况、深度、速度条件下被发现的概率,并进行分析。仿真结果表明,该分析对使用水下航行体的作战指挥人员具有指导意义。

Aiming at the problem that the underwater vehicle is easy to be detected by the enemy’s high-altitude remote sensing detector when it performs specific tasks,the detection probability of its wave-making wake is analyzed.On the basis of analyzing the formation mechanism of wave-making wake,according to the potential flow theory,the point source problem of fluid is analyzed by using Green’s function,and the wave-making wake model of underwater vehicle is established.According to the sea wave model and the energy bisection method,the signal to noise ratio was extracted by simulating the random sea surface,and the exposure probability model of the underwater vehicle found by the high-altitude remote sensing detector was constructed,and the discovery probability under different sea conditions,depths and speeds was simulated and analyzed.The simulation results show that the analysis has guiding significance for combat commanders who use underwater vehicles.
