In the framework of the inverse scattering methodologies, this paper is aimed at preliminarily assessing the integration between the Iterative Multi-Scaling Approach and the Level-Set-based method. In order to enhance the potentialities of the Level-Set-based minimization, a multi-resolution procedure is employed for allowing a finer discretization only in those regions of interest where the scatterers are located thus reducing the whole computational burden with respect to a singe-resolution approach. In order to demonstrate the effectiveness of the IMSA Level Set technique, a set of representative numerical results are presented and discussed.

Abstract
In the framework of the inverse scattering methodologies, this paper is aimed at preliminarily assessing the integration between the Iterative Multi-Scaling Approach and the Level-Set-based method. In order to enhance the potentialities of the Level-Set-based minimization, a multi-resolution procedure is employed for allowing a finer discretization only in those regions of interest where the scatterers are located thus reducing the whole computational burden with respect to a singe-resolution approach. In order to demonstrate the effectiveness of the IMSA Level Set technique, a set of representative numerical results are presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
