摘　　要：海洋声场计算是海洋声学的重要研究课题,本文利用傅立叶变换推导了声场的平面波表示,平面波的传播可由相位进行表征,利用相位重构方法得到了声波在海洋中的传播情况并进行声场预报。利用典型深海声速分布模型检验该方法的有效性。Ocean acoustic field calculation is an important research subject in ocean acoustics, In this paper, the wave representation is derived using Fourier transform, Plane wave propagation can be characterized by phase,Situation of acoustic wave propagation is obtained by using the phase reconstruction method. The result approved the effectiveness of the method by typical deep - sea sound velocity distribution model.
