Abstract

The effect of the anisotropy of the spatial spectrum of wind waves on multiple scattering of acoustic modes in a refractive waveguide was studied. The attenuation of the coherent component of mode amplitudes and changes in their intensities and in the spatial-correlation coefficient are analyzed. The results of numerical modeling for the hydrological conditions of the Barents Sea in winter are presented. The results for the anisotropic wind-wave spectrum and a simplified model with an isotropic spectrum are compared.

浅海中各向异性风波对声模的多次散射效应

摘要

研究了风波空间谱的各向异性对折射波导中声模多重散射的影响。分析了模式振幅的相干分量的衰减及其强度和空间相关系数的变化。给出了冬季巴伦支海水文条件数值模拟的结果。比较了各向异性风波谱的结果和具有各向同性谱的简化模型。
