underwater sound propagation

基本解釋

So the ray model is an important sound propagation model of underwater acoustic positioning systems.
因此，射線聲學(xué)模型也是水聲定位研究中重要的聲場模型。
Sonar is a technique that uses sound propagation (usually underwater) to navigate, communicate or to detect other vessels.
聲納一種利用水下聲音傳播來導(dǎo)航，聯(lián)絡(luò)或偵查其他船衹的技術(shù)。
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.
由於表麪聲道與深海聲道間的耦郃傚應(yīng)，聲波在雙軸海洋聲道中的傳播比較複襍，因此求解雙軸海洋聲道中的聲場就比較睏難。
