摘　　要：为实现在复杂海洋环境中水下声场快速计算与可视化,对经典射线模型进行了改进。通过计算可随海底地形和声速剖面变化的声传播曲线与声场传播损失,设计了一套声场可视化软件,并结合实测海洋环境数据和地理环境数据,实现了声场传播损失与声呐探测能力可视化。该软件操作简单、稳定性高且处理速度较快,可用于水下预警、反潜作战和辅助决策等领域。In order to realize the rapid calculation and visualization of underwater sound field in com⁃plex marine environment,the classical ray model is improved.The sound field visualization software is designed by calculating the sound propagation curve and the sound field propagation loss that can vary with the seabed terrain and sound velocity profile,and the visualization of sound field propagation loss and sonar detection ability is realized by combining the measured marine environment data and geographical environment data.The software has the advantages of simple operation,high stability and fast processing speed,and it can be used in the fields of underwater early warning,anti⁃submarine warfare and decision⁃making assistance.
