| Abstract(in English) | In order to know characteristics of sound propagation in shallow water, it is necessary to use in accurate numerical method of sound propagation. We calculated the characteristics with Finite Difference Time Domain Method (FDTD method), because this method is very accuracy and comparatively useful for range-dependent model in shallow water. In this paper, we calculated the characteristics of sound waveform reflected sea bottom with transition layer in shallow water using bv FDTD method. |
