%X To investigate the problem of classical analytical method,which can not be used at Low-Grazing Angle(LGA)for rough surface scattering,a new high-order analytical method based on the high-order series expansion of the two-dimensional electric field and the profile function of rough surface is adopted.By this arithmetic,the co-polarized backscattering coefficient at LGA is compared with high-order Small Perturbation Method(SPM)and classical SPM,the grazing effect at different roughness is discussed,the modified effect for Gaussian rough surface at LGA is analyzed by high-order SPM and high-order Kirchhoff Approximation(KA).The result shows that the high-order analytical method is valid for LGA problem.At last,the vertical-to-horizontal Polarization Ratio(PR)with different power of secant function of grazing incident angle and scattering angle is considered particularly,and the classical expression of PR is rectified.
