Scattering of optical waves by a multi-scale rough mirror surface as a phase screen is considered. To solve the problem we used the diffusion phase approximation and numerical model of a phase jump. The scattering intensity was averaged over the ensemble of realizations. The results of numerical calculations of the angular dependence of the intensity are presented for a backscattering demonstrating the effect of the roughness distribution over the scales and its secondary impact on the indicatrix of scattering for multiplicative surface modulation.
