Microwave imaging of dielectric targets by means of an inexact-Newton method in Lp banach spaces and multifrequency processing

By Alessandro Fedeli, Matteo Pastorino and Andrea Randazzo

Abstract

The reconstruction of the distributions of the dielectric properties of unknown targets by using interrogating microwaves is a topic that has been widely investigated by the scientific community in the last years (M. Pastorino, Microwave imaging, John Wiley, 2010). In this framework, the present authors have developed an approach based on an inexact Newton method (C. Estatico et al., IEEE Trans. Antennas Propag., 60, 2012, pp. 3373-3381), which has been found to be quite efficient in finding a regularized solution of the associated electromagnetic inverse scattering problem with a spatial resolution beyond the Rayleigh limit (since it is developed in the spatial domain)
