摘要: 提出了一种基于面积差的声速剖面自适应简化方法。首先,研究了不同声速剖面之间面积差与声线跟踪误差间的关系,建立了二者关系模型;然后,给出了基于跟踪精度约束的声速剖面简化方法和流程;最后,对该方法开展了试验验证,在无人工干预的情况下,方便地实现了声速剖面的简化,显著地提高了测深数据处理效率。

Abstract: An adaptive method based on area difference is proposed. Firstly, the relationship between area difference and sound ray tracking bias is studied and the model is built. Then the simplification method and procedure of SVP are provided, which are based on the constraint of sound ray tracking accuracy. Finally, a deep water experiment is conducted to verify the proposed method and the simplification process is easily achieved without manual intervention. It improves the efficiency of bathymetric data processing remarkably to carry out ray-tracing with simplified sound velocity profile.

Key words: sound velocity profile simplification, area difference, equivalent sound velocity profile, sound ray-tracing bias
