Three-dimensional problem of inverse scattering in stratified randomly inhomogeneous media

Conclusions The problem with a stratified medium is of immediate interest in acoustics (in particular, marine acoustics), just as it is in radiophysics [8], but its importance consists primarily of the fact that it permits closely fitting a solution of a problem with three-dimensional inhomogeneities.One can isolate the characteristic facts associated with IS in stratified media. In the first place, spatial-temporal scales arise which restrict the region of applicability of the approximate methods. Outside this region the approximate methods do not work due to accumulating effects, and, secondly, fluctuations of the IS intensity increase there. It would be very timely to investigate, in this respect, media with three-dimensional inhomogeneities, which is necessary for problems of probing randomly inhomogeneous media by the IS method.Pacific Ocean Oceanological Institute, Far East Scientific Center, Academy of Sciences of the USSR.
