| 中文摘要: |
| 声源运动会引起海底混响产生显著的多普勒现象。本文基于绝热简正波和射线模式类比计算浅海海底入射声场和散射声场，将多普勒频移引入简正波理论，分析海底散射截面的多普勒频谱贡献，建立了运动声源的浅海混响功率谱模型，利用海上实验数据验证了该模型。 |
| 英文摘要: |
| The moving of the transmitter will cause a significant Doppler phenomenon of seabed reverberation. In this paper, the incident sound field and the scattered sound field of the shallow water seabed are calculated based on the adiabatic normal mode and the ray-mode analogy. The Doppler frequency shift is introduced into the normal mode theory, and the Doppler contribution of the seabed scattering cross section is analyzed. A model of the shallow water reverberation power spectrum for a moving sound source is established, and the model is verified by the sea experimental data. |
