Some features of backscattering in a reflective layer with multiscale random irregularities

Abstract

Using previously derived formulas describing wave reflection and scattering in a reflective multiscale inhomogeneous layer, we examine the effect of random irregularities on the sounding signal structure. It is shown that, unlike scattering in a homogeneous medium, scattering by small-scale irregularities in a plane-stratified medium depends on the location of these irregularities relative to the reflection point. This largely determines the scattered pulse structure and the applicability of the geometrical optics approximation to its description
