A computer-diagnostics method for examining characteristics of surface layers in conducting extended solids, based on treating data on radio-wave scattering by these solids in the meter and centimeter bands, is reported. The problem is reduced to solving a system of nonlinear algebraic equations. The computational algorithm and results of numerical experiments are described. The method allows using, as input data, not only asymptotic scattering diagrams, but also amplitude values of the reflected field measured close to the surface under study. The latter improves solution stability in complex noise-signal situations in which random distortions in receive chains occur.
