摘      要：A widely used iterative technique named the Method of Ordered Multiple Interactions is given for calculat-ing the Gaussian-like beam scattering from a time-varying sea surface with the Pierson-Moskowitz (P-M) spectrum. Thisis done by solving the magnetic field integral equation for the current induced on an infinite rough surface. Following thediscretization of the integral equation, the unknown currents can be determined more rapidly with the LU *** results are presented with emphasis on the electromagnetic backscattering at low grazing angle incidence. Itis shown that the backscattering cross section is proportional to the nearly fourth power of the grazing angle for thebackscattering cross section with a different beam waist, surface length, and velocity of the wind are
