This paper presents a two stage strategy for the electromagnetic imaging of unknown lossless profiles. The first step is aimed at providing the localizations and an estimate of the number of the regions�]of�]interest (RoIs) where the scatterers are supposed to be located through the application of the DORT method enhanced with a suitable processing of the information associated with the eigenvalues of the time reversal operator. Towards this aim, a suitable procedure is developed and applied in an extended and unsupervised fashion for localizing the finite�]dimension scatterers under test. Successively, the second stage is devoted to reconstruct the unknown scatterer distributions by means of an iterative multi�]resolution non�]linear inversion performed only in the RoIs determined during the previous step.
