Abstract

characteristics of Gaussian beam scattering from the target, which is the statistical average and mutual correlation function of the statistical characteristics. Under the laser beam incidence, numerical method is used to calculate the correlation function of a sphere are change with scattering angles in different radii, material, incident condition, and so on. The mutual correlation functions of metal materials are larger than that of non-metallic materials. There have a stronger backward-scattering of metal sphere and a stronger forward-scattering of non-metallic sphere. Roughness of material surface and dimension of sphere have bigger influences on the correlation functions of scattering fields. And mutual correlation functions have same distribution in different polarization. Our works will be further be based on studying other high order statistical moments of laser beam scattering from target with rough surface.
