underwater sound propagation

基本解释

So the ray model is an important sound propagation model of underwater acoustic positioning systems.
因此，射线声学模型也是水声定位研究中重要的声场模型。
Sonar is a technique that uses sound propagation (usually underwater) to navigate, communicate or to detect other vessels.
声纳一种利用水下声音传播来导航，联络或侦查其他船只的技术。
Because of the coupling between surface channel and SOFAR channel, sound propagation in two, axis underwater channel is complex and calculation of acoustic fields is difficult.
由于表面声道与深海声道间的耦合效应，声波在双轴海洋声道中的传播比较复杂，因此求解双轴海洋声道中的声场就比较困难。
