Abstract：According to the Kirchhoff approximation for the rough surface scattering and by calculating the shadowing function and characteristic function of the fractal rough sea surface, the formula of the scattering cross section for the conducting fractal sea surface is derived with consideration of the shadowing effect. The influence of the shadowing effect for different RMS slope of the surface is investigated. The distribution of the scattering cross-section for the Gaussian rough surface and fractal rough sea surface is compared with millimeter wave incidence. The angular distribution of the bistatic scattering cross-section from fractal sea surface for different fractal dimension and different spatial frequency is analyzed. The influence of different incident angle, different fractal dimension and shadowing effect on the Doppler spectra of the echo from the fractal sea surface is discussed in detail.
