Ocean acoustic application of high-resolution global quasi-real-time ocean hydrological data
For the needs of real-time evaluation of ocean acoustic performance,a study is carried out in this paper by using the high-resolution global quasi-real-time ocean hydrological database and taking a certain sea area in China as the research object.Combined with the three-dimensional visualization high-resolution terrain/sea depth information in the two selected research areas about 300 m and 4 000 m water depths,the regional acoustic environment information is obtained by using the global high-resolution quasi-real-time Hybrid Coordinate Ocean Model data of ocean temperature,salinity,and depth.The processing times of the industrial computer for bathymetric and hydrographic data are 0.70 s and 0.03 s respectively,which meet the requirements of rapid application in practical engineering.By inputting quasi-real-time acoustic environment information into the underwater acoustic ray model,the simulation results of the underwater acoustic field in the selected shallow-sea area about 300 m depth and deep-sea area about 4 000 m depth are obtained,which can be applied in the acoustic performance evaluation of marine equipment and guide the use of acoustic equipment.This research method can facilitate the performance evaluation of current acoustic equipment and has important practical application value.
