海洋内波对水声场的扰动

Disturbance of water sound field by ocean internal waves

针对海洋内波对水声传播影响的问题 ,在简要引出内波方程、水声方程和内波解、射线理论之后 ,以水深 2 10 0m等V is l 频率的全板造波内波解对双线性水声剖面情况计算了内波和内波对声场及声线传播的影响。结果表明 。

The gist of the article is to describe the effect of ocean internal waves on water sound propagation. The internal wave equation, water sound equation, the solution of internal waves, and sound ray theory are introduced briefly in this paper. The internal wave solution, sound field and the effect on sound ray propagation are calculated for internal waves make by method of wave making with the whole panel water depth h =2 100m and Vtsl frequency N =constant. The steady sound velocity profile is taken as double linear distributions. The results show that the effect of internal waves on the track and time of sound ray propagation is not neglected.
