摘要
In this paper, an introduction is given of the fractal theory anti its application to the description of the surface condition. Moreover, a simulation is made on the gauss surface, with the root-mean-square height and correlation length as the basic parameters, to draw the graph of the surface condition for the purpose of calculating by the method of MC the spatial scattering intensity distribution in different incidence angles of different patterns on a rough surface in the constraint condition of Kirchhoff approximation. Finally, a measurement is made on the surface BRDF of granite by means of experiment, and a comparison is made between the academic values and the experimental values.
