Comparative Study of the Measured Data and Electromagnetic Scattering from Two-Dimensional Sea Surface Based on Improved Wen's Spectrum

WU Geng-Kun;JI Guang-Rong;CHENG Xiao-Long;College of Information Science & Engineering,Ocean University of China;  
By combining the Wen's spectrum and the Donelan's experimental conclusion,a two-dimensional sea surface model suitable for different depths and different stages of wave growth is proposed based on the classical Monte Carlo algorithm in this paper.In previous works,based on the classic twoscale method for the calculation of sea backscattering coefficient,introducing the simulation results obtained by the SSA method,the electromagnetic scattering calculation method was modified.Compared with the fitting result based on the backscattering coefficient model of GIT,it proves that the improved Wen's spectrum suits Chinese coastal waves and the proposed electromagnetic scattering theory is accurate and efficient.In this paper,based on the classic two-scale method for the calculation of sea backscattering coefficient,we compared the calculation results with Nathanson's measured data,and then analyzed the electromagnetic scattering characteristics of two-dimensional random rough sea-surface under different sea states,grazing angle,carrier frequency and polarization mode.In summary,the method in this paper for simulating sea surface based on the classical Monte Carlo algorithm is consistent with the actual sea surface when the sea state changes along with the wind speed and the wind area.On the basis of this work,the backscattering coefficient result calculated by the two scale method is similar to the measured data,and in this paper,the electromagnetic scattering characteristics of two dimensional rough sea surface are in conformity with the actual physical laws.Proved by experiments,the method proposed in this paper is effective,and has the actual physical meaning.
