Abstract
The method of solving the light scattering problem in the backscattering direction within the framework of physical optics approximation has been considered. The recommendations on preliminary estimate of the contribution geometrical optics beams to the backward direction that can reduce the number of the beams for the calculation has been given. Presented empirical estimates and the guidelines for choosing the optimal step of numerical integration can significantly reduce the resource consumption of the physical optics method. The results of the solutions of the light scattering problem are available free in the form of a data bank of the Mueller matrices.
