文摘A reverberation model for estimating the average reverberation intensity in layered shallow water is presented.The reverberation intensity is calculated in terms of ray theory for short range and normal mode theory for long range. The calculation accuracy has been improved by taking into account the effect of complex eigenvalues on the incident normal mode field. From the comparison between different scattering models it has been shown that the separable bistatic-backscattering model is acceptable. This makes it possible to calculate reverberation by using only the monostatic-backscattering coefficient and to save greatly the computing time.
