Inverse scattering for a random potential

Abstract

In this paper we consider an inverse problem for the nn-dimensional random Schr\"{o}dinger equation (Δq+k2)u=0(\Delta-q+k^2)u = 0. We study the scattering of plane waves in the presence of a potential qq which is assumed to be a Gaussian random function such that its covariance is described by a pseudodifferential operator. Our main result is as follows: given the backscattered far field, obtained from a single realization of the random potential qq, we uniquely determine the principal symbol of the covariance operator of qq. Especially, for n=3n=3 this result is obtained for the full non-linear inverse backscattering problem. Finally, we present a physical scaling regime where the method is of practical importance.
