Abstract: Sea bottom reverberation is studied,and the principle of forming reverberation is analyzed.By utilizing ray theory,a general sea bottom reverberation network model with intuitionistic physics signification is constructed.Combined with "reciprocity property",an incoherent sea bottom reverberation model for monostatic is presented,the simplified model is applied to forecasting reverberation signal and calculating average reverberation intensity,the simulation results show the efficiency of the method.
