Imaging of scatterers using canonical correlations

Abstract

There is much interest in the application of subspace-based signal processing techniques for wavefield imaging of scatterers from the scattering matrix [1], [2], [3], [4], [5], [6], [7]. These approaches are part of the modern focus on so-called “qualitative” methods in inverse scattering [8]. Most of these methods are valid in the exact scattering regime including multiple scattering in which the inverse scattering problem is nonlinear.
