| 中文摘要: |
| 在声传播测量中，在测线上水深的较大变化，使声传播损失发生显著的变化。海底山和海底凹陷地形对声波的传播有较大影响，使声传播损失出现变大和变小的情况，甚至产生较大的声影区效应，对水声装备的研制和使用有重大影响。对一种特殊海底山地形下的声传播问题进行分析，并结合实验数据对比有无海底山情况下的声传播损失，期望对海洋环境测量和水下武器装备的研制及应用有所启发。 |
| 英文摘要: |
| In underwater sound propagation measurements, the great change of water depth along the measuring line can make the sound propagation change significantly. So, the topography of seabed mountains and trenches has a great influence on the sound wave propagation to make the sound transmission loss become larger and smaller, and even produces acoustic shadow effect, which has a great influence on the development and use of underwater acoustic equipment. In this paper, the sound propagation problem under a special seabed mountain terrain is analyzed, and by comparing with the experimental data, the sound transmission loss in the presence or absence of seabed mountain is studied. It is expected that this study will be helpful to the marine environmental survey and the development and application of underwater weapon equipment. |
