Abstract

By using the method of the angular power spectrum for shallow-water averaged sound field, the vertical coherence of shallow-water long-range reverberation was calculated.The relations between the cross-correlation coefficient of the reverberation and relevant parameters such as boundary reflection and scattering, distance(or time),hydrophone separation and signal fregnency etc are given. The results would be helpful for analysis of the angular dependence of bottom(or surface) scattering at low grazing angle in shallow-water environmen.
