A combined strategy for the reconstruction of dielectric targets at microwave frequencies is proposed. It is based on the hybridization of a two-probes measurement approach, which includes a phase-retrieval technique, with an inverse scattering method based on an inexact-Newton algorithm. The proposed strategy is aimed at taking advantages of the good regularization capabilities of the considered inverse scattering method with the effectiveness of the twoprobes approach toward the idea of developing a simple and low-cost imaging setup. The formulation of the proposed combined method is reported together with some experimental validations.

Abstract
A combined strategy for the reconstruction of dielectric targets at microwave frequencies is proposed. It is based on the hybridization of a two-probes measurement approach, which includes a phase-retrieval technique, with an inverse scattering method based on an inexact-Newton algorithm. The proposed strategy is aimed at taking advantages of the good regularization capabilities of the considered inverse scattering method with the effectiveness of the twoprobes approach toward the idea of developing a simple and low-cost imaging setup. The formulation of the proposed combined method is reported together with some experimental validations.
