Abstract
The integration of the Iterative Multi-Scaling Multi-Region (IMSMR) procedure and the Inexact-Newton method (INM) is proposed within the contrast-field formulation of the inverse scattering problem. Thanks to its features, such an implementation is expected to effectively deal with the reconstruction of separated objects. A selected set of numerical results is presented to assess the potentialities of the IMSMR-INM method also in comparison with previous INM-based inversions.| File | Dimensione | Formato | |
