摘要


基于射线声学理论建立了运动介质中的三维声线传播模型作为正演模型,在利用双向声传播时延差计算海流流速分量时,对目前已有的时延差计算海流的方法进行改进,考虑了海流对本征声线影响,改进后的计算方法可在收发双方本征声线不同的情况下计算出海流流速,同时可以获得声传播方向上的流速垂直分布结构.最后通过仿真验证了海流计算方法的可行性. A three-dimensional sound propagation model of the moving medium is proposed by using the ray theory. The two-way sound propagation delay is used to calculate the velocity of ocean currents. By considering the influence of ocean currents on eigenrays, the current inversion method is improved so that it can deal with the situation, while the eigenrays are different for the sender and receiver, and then it is possible to get the vertical structure of ocean currents in the sound propagation direction. Simulation results are verified by the experimental results.
