给出了舰船噪声不同中心频率窄带包络间相关系数（频间包络相关）R和滤波中心频率差值（频差）△fni、起始滤波中心频率fn的值、滤波带宽△f以及时延τ的关系,并和海洋环境噪声的R～△fni曲线进行了比较。结果表明,舰船噪声频间包络相关和海洋环境噪声频间包络相关有显著差异。
The value of the difference (frequency difference) R and the center frequency fn of the initial filter center between the narrow band envelope of different center frequencies of the ship noise and the filter center frequency fn And time delay τ, and compared with R ~ △ fni curve of marine environmental noise. The results show that there is a significant difference between the envelope correlation of ship noise and the envelope of marine environment noise.
