On the basis of the theories of the ocean surface specular-point scattering and slopes distribution and by applying the Gram-Charlier distribution of ocean surface slopes to make a model for the ocean surface specular-point scattering and taking wind speed at 10m above ocean surface as basis, we establish a calculation method for the radar backscattering cross-section of the ocean surface specular-point scattering model based on the Gram-Charlier distribution. By comparing with measured data, we verify accuracy and applicability of the ocean surface specular-point scattering model based on the Gram-Charlier distribution. By simulation study, we summarize the variety regulations of the ocean surface specular-point scattering systematically under different conditions that include wind speed, wind direction, polarization, wave band, angle of incidence, azimuth and so on, and have function of guiding practical application.
