Modeling of reverberation in shallow-water based on the beam tracing theory

A reverberation intensity model and a reverberation series model in shallow-water based on the beam tracing theory were presented.The brief theoretical deduction to compute reverberation intensity was given,and the results were compatible with the measured data. The reverberation series simulation method was built and its characteristics were tested with the measured data and other results that had been verified.The studies show that the reverberation intensity model can be used to forecast shallow-water reverberation intensity,and the reverberation series simulation method can generate reverberation series which mostly properties, such as probability distribution,time-varying spectrum,and spatial correlation,agree well with the measure and the theory.
