| Abstract: | The Rayleigh distribution model and K distribution model were introduced.The monostatic reverberation model was deduced based on the physical scattering.The simulation of the mathematical model was carried on through the CW and the LFM signal.And the fitting test of the Rayleigh distribution and K distribution was based on the simulation data.Then the test data from lake-test was for the fit test of the Rayleigh distribution and K distribution after processed,which validates the reverberation mathematical model and the simulation method.The results showed that K distribution model can more accurately describe the statistical properties of the seafloor reverberation. |
