应用于鱼雷远程报警的鱼雷出管信号检测

Analysis of the Launching Torpedo Noise Affecting the Torpedo Hit Probability

潜艇在进行鱼雷攻击时发射噪声高于环境噪声,如果能及时检测到此时鱼雷的出管信息将有利于提高鱼雷的报警距离。针对鱼雷发射时瞬态噪声的特点,分析了基于高阶谱、双谱和小波分析等几种信号检测方法,探讨了进行鱼雷出管信号检测的可行性和有效性,该方法的应用将极大提高舰艇的防御能力。

The noise of the launching torpedo on the submarine is high than environment noise, which could increase the distance of the torpedo warning to the ships if the information of the tube-exit of torpedo has been detected in time. According to the characteristic of the transient noise, the paper analyzed the available methods of signal detection based on the high-order spectrum, bispectrum estimation and wavelet transform, which can greatly improve the defendable ability of the ships against torpedo.
