水下基阵探测空中噪声目标建模仿真

针对水下基阵探测空中噪声目标的可行性问题,运用建模与仿真实验的手段进行了定量研究,通过建立声波由空气向海水入射的能量传播模型、海洋环境噪声模型、水下基阵的指向性增益和检测阅模型,通过仿真实验得到了当基阵检测阈及指向性增益变化时,水下对空中噪声目标的探测距离曲线,通过分析发现:在现有检测方式下,水下基阵直接探测空中噪声目标非常困难,难以对空中噪声目标实现远程预警.

Modeling and Simulation of Underwater Sonar Array Detects Radiation Noise of Aerial Target

In order to research the feasibility of underwater sonar array detects radiation noise of aerial target, it founds model of sound transmit from air to seawater, ambient noise of ocean(NL), detect threshold(DT) and direction index(DI) of underwater sonar array, gets quantificational result through modeling and simulation means.receives the result of detection distance curve when DT or DI of underwater sonar array change.Draw the conclusion:it is difficult to detect or achieve long-distance alertness to aeria...
