| 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 current application of ocean engineering, and can play a certain role in guiding future research. |
