Beam Domain Formulation for Tomographic Inverse Scattering. Part II: The Inverse Problem

In this two-part paper we present a local inverse scattering approach using pulsed-beam frame (PBF) processing. In Part I we explored the beam-domain representation of the scattered fields and demonstrated that within the Born approximation, the beam-domain data is proportional to the local Radon transform of the medium. In this Part II we use this result and present a local reconstruction algorithm using pulsed beam back-propagators.
