The average coefficient of light scattering by surface fractal structures is calculated within the scope of the Kirchhoff’s method. Two-dimensional band-limited Weierstrass function is used to simulate a scattering surface. On the basis of numerical calculations of average scattering coefficient, the scattering indicatrixes for various surfaces and incidence angles are calculated. The analysis of the indicatrixes leads to the following conclusions: the scattering is symmetric about the incidence plane; with the increase of surface calibration degree, the scattering pattern becomes more complicated; the greatest intensity of the scattered wave is observed along the mirror direction; there are other directions, in which the intensity bursts are observed.
