Single-step approach to phaseless contrast-source inverse scattering

Abstract

An enhanced phaseless approach to the inverse scattering algorithm, starting from the Contrast-Source formulation of the Electric Field Integral Equation, is presented in this work. It fully exploits the available measurements of the amplitude-only total field, combined with the known complex incident field, to implement a single-step procedure able to reconstruct the target profile by avoiding the usual phase-retrieval process.
