摘要 宽带声传播、匹配场定位、水下环境仿真等技术的发展对水声传播提出了越来越高的要求,如何开发快速准确并与实际海洋环境条件相吻合的三维声传播模型,并充分利用现代计算机技术实现声传播的快速计算已成为水声技术的一个重要研究方向。基于波束位移射线简正波(BDRM)理论,将射线-简正波方法和简正波-抛物方程方法结合起来,建立三维射线-简正波-抛物方程模型,同时为满足三维声场计算的时间需求,设计了射线-简正波-抛物方程模型并行算法,在高性能集群系统上的测试分析结果表明,设计的并行算法具有较高的并行计算效率。 With the development of theory and technology of broadband sound propagation, matched-field source localization and underwater environment simulation, an efficient method for sound field calculation is very important. Based on beam-displacement ray-mode theory, combining ray-mode theory and mode-parabolic equation method, 3D ray-mode-parabolic equation theory was established. And the parallel algorithm of ray-mode-parabolic equation model was designed. Computer experiments and performance analysis on high performance computer show that the parallel program increases parallel efficiency and good expansibility.
