摘要：

This paper presents an underwater acoustic communication channel model to reveal the influence of rough bottom reflection and scattering on the channel. We analyze experimental data from two channel measurement campaigns, and concentrate on the channel properties such as the spread-Doppler function, the time coherence function and the spatial coherence function to study the variations induced by medium inhomogeneity and random scattering of the rough bottom. It is found that the time-varying channel impulse response can be explained by using forward scattering theory under downward refracting sound velocity and mountain seabed condition, and the experimental results show good match to our model.
