【Abstract】 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.更多还原
