This paper considers the problem of scattering of electromagnetic waves on the object, which is a plate coated with an absorptive coating. The system of integral equations was recorded, which allows us to associate a density potential, Green’s function and the incident electromagnetic wave. After solving the system of equations based on the method of moments were calculated values of the effective area of the dispersion under certain conditions of observation. Based on the view object, that use the facet model and gives suggestions for characteristics of a subsystem of CAD, in which you can carry out the design of objects with the required values for the levels of scattered electromagnetic fields were obtained. As input to this subsystem can be used the sizes of the facets, the sector angles, the required level for the characteristics of scattering of radio waves.

Keywords: scattering of radio waves, facet model, CAD, radar cross section, absorption of radio waves.
