Nonparametric estimation of the heterogeneity of a random medium using compound Poisson process modeling of wave multiple scattering

Abstract

In this paper, we present a nonparametric method to estimate the heterogeneity of a random medium from the angular distribution of intensity of waves transmitted through a slab of random material. Our approach is based on the modeling of forward multiple scattering using compound Poisson processes on compact Lie groups. The estimation technique is validated through numerical simulations based on radiative transfer theory. © 2009 The American Physical Society.
