摘　　要：为了直观且快速评估深海条件下海底地形和海深对海底声学设备的影响,本文主要将高精度海底地形数据库、水文数据库与声学工具包结合,研究有利于海底声学设备效能发挥的布设方案。高精度海底地形/海深数据库主要采用Sandwell&Smith地形/海深数据库,本文在所选区域通过插值方式获得更高精度的地形/海深信息,并将海底声学设备的布设路径进行可视化展示,便于工程人员查看。水文数据主要采用中国科学院大气物理研究所发布的海洋环境相关数据库,本文将可视化海底地形/海深结合声学工具包,用于海底声学设备评估,可以直观地展示声波在复杂地形和不同深度下的传播路径和特性。对海底声学设备的布设区域进行可视化呈现,可以更好地分析地形和海深对声学设备布设的影响,这对当前的海洋工程应用具有一定的指导作用。In order to visually and quickly assess the impact of seafloor topography and sea depth on submarine acoustic equipment under deep-sea conditions,this paper principally combines a high-precision seafloor topographic database,a temperature-salt-depth sound velocity database and a hydrographic database with an acoustic toolkit.Furthermore,it researches the deployment of favorable programs that are conducive to the performance of submarine acoustic equipment.The Sandwell&Smith topography/sea depth database is utilized for the high-precision seabed topography/sea depth database,which accurately reflects the complexity of the seabed topography and ensures the reliability of acoustic analysis.The paper further enhances the resolution of topography and sea depth information through interpolation in the designated area,facilitating the visualization of the deployment trajectory of seabed acoustic apparatus.This enhances the accessibility and comprehensibility for engineers,thereby streamlining the evaluation of acoustic performance.The enhanced visualization of acoustic performance enables engineers to refine the analysis,thus enhancing its precision.The utilization of hydrographic data,predominantly sourced from the database on the marine environment released by Institute of Atmospheric Physics,Chinese Academy of Sciences,serves as a fundamental basis for the study.The proposed approach involves the integration of a seabed topography/sea depth visualization toolkit with an acoustic toolkit,commonly employed for the assessment of submarine acoustic equipment.This integration facilitates the visualization of acoustic propagation paths and characteristics of sound waves in complex terrain and at varying depths.The deployment area of undersea acoustic equipment is visualized and presented through 3D visualization and dynamic simulation,which can be used to better understand and analyze the impact of terrain and sea depth on the deployment of acoustic equipment.This has important research and practical significance for the c
