Fluctuations of a wavefield propagating in a medium with random largescale (in comparison with the wavelength) inhomogeneities rapidly grow with distance because of multiple forward scattering. Perturbation theory in any version fails beginning from certain distance (the boundary of the region of strong fluctuation). Strong fluctuations of intensity can appear in radiowaves propagating through the ionosphere, solar corona, or interstellar medium, in occultation experiments on transilluminating planet’s atmospheres when planets shadow natural or artificial radiation sources, and in a number of other cases.
