摘　　要：应用傅立叶综合方法和波束跟踪理论,研究了分层介质中运动声源和接收器的宽带脉冲声传播,根据运动声源和接收器声传播的简正波理论,导出了基于波束跟踪方法的运动声源和接收器宽带脉冲声传播表达式。结合实例计算分析了宽带脉冲声传播的特点,并与宽带简正波的计算结果进行了比较,二者符合较好,证明了这一仿真模型的有效性。The propagation of broadband impulsive sound was studied with moving source and receiver in stratified ocean waveguide with Fourier synthesis and beam tracing theory. A representation of broadband impulsive sound propagation with moving source and receiver was derived based on beam tracing theory with reference to normal-mode propagation of moving source and receiver. Characteristics of broadband impulsive sound propagation were analyzed with theoretical analysis and results of some examples. And the results accord well with that of broadband normal-mode which validates this simulation model.
