| 摘 要： | 文章建立了水—沉积物—海底半空间的分层海底模型,通过仿真计算,比较了声波在海水和沉积物中接收时的传播损失差异。结果表明,在高声速海底的条件下,声波在沉积物中传播且频率较低时,传播损失较低,即低频声波更易于在沉积物中传播。

| Abstract: | A seabed is selected to establish a model of layered bottom which is composed of water-sediment with high acoustic velocity-half-space with high acoustic velocity.The difference of acoustic transmission loss in the water and in the sediment is compared by simulation analysis.A conclusion is drawn that transmission loss is lower when acoustic wave is propagated in the sediment and its frequency is low.In other words,acoustic wave with low frequency is easier to propagate in the sediment than propagate in the... |
