摘要
本文研究海洋环境噪声与舰船噪声的频间相关与群延迟特性。理论与实验结果表明,舰船辐射噪声的频间相关远大于海洋环境噪声的频间相关,远距离舰船噪声的频间相关存在显著的群延迟。
The characteristics of frequency correlation and group time delay of ambient noise and ship radiated noise in the sea are studied. The theoretical and experimental results show that the frequency correlation o f ship radiated noise is much greater than that of ambient noise, and the frequency correlation of ship radiated noise at long distance has obvious group time delay.
