Abstract

A normalized 2D band-limited Weierstrass fractal function s used for modeling the rough surface Based on Kirchhoff theory, an analytic solution of the average scattering field and the variance of scattering intensity are derived, the influence of fractal dimension, the patch size of the surface and the fundamental wavenumbers on the scattering field is discussed by theoretical analysis and numerical calculations. The fractal dimension D, which determines the surface roughness, will control the distribution of scattering pattern. Emphasis is also put on to examine the relation of fractal dimension with the variance of scattering intensity. The important conclusion is obtained that the diffracted envelope slopes of scattering pattern can be approximated to a slope of linear equation.
