The integration of the inexact Newton method within a multiscaling strategy is assessed in the framework of the contrast-field formulation of the electromagnetic inverse scattering.

Abstract
The integration of the inexact Newton method within a multiscaling strategy is assessed in the framework of the contrast-field formulation of the electromagnetic inverse scattering. By using the features of the integrated approach, the technique is expected to suitably face the nonlinearity and the illposedness/ill-conditioning issues of the imaging problem. A numerical validation dealing with experimental data related to different objects is carried out to provide evidence of the method premises pointing out features and potentialities as well as current limitations. © 2011 Wiley Periodicals, Inc.File | Dimensione | Formato | |
