A new methodology based on an iterative multiscaling for microwave imaging

Multi-Resolution Retrieval of Non-Measurable Equivalent Currents in Microwave Imaging Problems-Experimental Assessment

“…, V , are collected on a set of M (v) electromagnetic sensors located in an external observation domain Γ obs . The IM SA presented in [20,[32][33][34][35][36] considers a succession of s = 1, . .…”

“…Moreover, ε R and σ are the relative permittivity and conductivity, respectively, and ε 0 is the permittivity of the free-space. In denote the discretized Green's operators [20]. Moreover, A n(i) (or A u(i) ) is the area of the n-th (or u-th) cell at…”

On the Effects of the Exploitation of Source Diversity in Aspect Limited Multi-View Microwave Imaging Systems

“…Consequently, the Iterative Multi-Scaling Approach (IMSA) (investigated in [20] [21] for the single-source case) has been customized for satisfactorily processing the enlarged multi-source (MS) dataset. This paper will be structured as follows; in Sect.…”

“…Moreover, the minimization of the MS cost function has been performed profitably integrating the proposed approach into a Multi-Scaling inversion scheme previously proposed for dealing with single-source multi-illumination/multi-view experiments [20] [21]. Such an integration is aimed at:…”

“…The supports of the Regions-of-Interest (RoIs) of the investigation domain where the resolution level is increased are defined iteratively and adaptively according to the information that is acquired processing intermediate reconstructions of the object function [20]. The scattering data have been synthetically-generated by considering the following electromagnetic source models:…”
