Abstract

Using a combination of the Fock proper-time method and the double weighted Fourier transform, we have derived a solution of the problem of wave reflection from a regularly inhomogeneous layer with random irregularities. The report uses this solution to determine the mean field and the frequency coherence function. The condition of applicability of the geometrical optics approximation for the frequency coherence function in the narrowband case is much weaker than that for individual realizations. We report the simulation results for the Gaussian spectrum of irregularities and for Shkarofsky's model.
