Abstract

Firstly, the geometric model of linear sea surface is constructed based on linear wave theory and linear filtering method. At the same time, considering the nonlinear characteristics of sea waves, the modified model of nonlinear sea surface is introduced. By comparing the shape and statistical characteristics of nonlinear sea surface with linear sea surface, the Doppler echo spectrum of sea surface electromagnetic scattering is calculated, and the Doppler spectrum characteristics of dynamic sea surface scattering echo signals under different initial conditions are analyzed. Finally, the model simulation data are compared with the measured sea state data. The results show that the calculation results based on nonlinear sea surface are more consistent with the experimental data.
