摘　　要：针对水声环境对舰艇声纳探测效能的显著影响以及主要海域海洋环境特点,建立了浅海和深海水声环境仿真模型,实现了对海区水声环境的快速、准确预报。提出了基于3维声场纹理预积分的水声环境体可视化方法,实现了对水下声场的直观表达与多维分析,从而为水声环境的认知、教学训练以及决策支持提供了有效手段。Aiming at the strong influence of underwater acoustic environment for the power of sonar detecting and the ocean environmental feature of ocean battlefield, the simulating models of sound propagation in shallow water and deep sea were established, which provided rapid and accurate prediction of underwater acoustic environment for navy operation. Based on the three dimensional sound field textures the pre-integrated volume rendering method was pro- posed. The method gave an intuitionistic description and analysis for the spatial structure of sound field and offered an efficient way for awareness, simulating training and operational decision of underwater acoustic environment.
