摘　　要：水下声脉冲的频谱是影响水声传播的重要因素,低频声脉冲具有辐射性强的特点。通过对水下声脉冲信号建模仿真,分析了影响信号频谱的参数,得到信号参数与信号频谱的变化规律,并且分析了水下等离子体声源参数对声脉冲信号频谱的影响,为今后水下等离子体声源的研制提供了参考。The frequency of acoustics pulse underwater is the important factor. The low frequency acoustics pulse has a characteristic of high emission. Through the modeling and simulation of acoustic pulse signals in water, the influence the parameters of the signal spectrum is analyzed, received the changing rule between the signal parameter and the signal spectrum, and the influence of the parameters of underwater plasma acousticssource on the signal spectrum is analyzed,the reference for the development of underwater plasma acoustiessource is provided for the future.
