海底底质声学参量是影响浅海中声传播的主要原因之一. 基于一次海上实验中的声传播损失异常现象, 提出了海底底质水平变化的海底模型, 并很好地解释了实验中观测到的现象. 研究结果表明, 海底底质在传播路径上的变化对于水中声传播的影响很大, 在进行声传播问题研究及海底反演中海底模型的选取都应对实际海底的水平变化特性予以足够的重视.
The acoustic parameters of the sea floor sediment are one of the main factors affecting the sound propagation in the shallow sea.Based on the anomaly of the acoustic propagation loss in a sea experiment, a submarine model of sea floor sediment level variation is proposed and well explained in the experiment .The results show that the variation of the seabed sediment in the propagation path has a great influence on the sound transmission in the water, and the selection of the seabed model in the research of acoustic propagation and undersea inversion should be enough for the horizontal variation of the actual seabed The importance of.
