A physical model for the electromagnetic scattering from large-scale rough surface of layered medium is established. Stratton-Chu integral equation and Kirchhoff approximation are adopted to calculate the electromagnetic scattering field. The Gaussian random rough surface is selected to simulate the actual rough surface of layered medium. The scattering echo is detected with a single-station nadir-looking radar sounder. The effects of surface and subsurface's roughness on the scattering filed are examined both theoretically and numerically. The effect of upper layer's electric properties (permittivity and conductivity) on the scattering field is also investigated and some analysis for the numerical results is presented.
