Microwave imaging systems: Three-dimensional reconstructions of dielectric targets

A full-wave three-dimensional microwave imaging approach is proposed in this paper. The method is based on the inversion of the full non-linear scattering equations that relate the measured scattered electric field data to the dielectric properties of the inspected volume. In particular, a Gauss-Newton scheme is employed, where the inner linearized problem is solved by using an iterative algorithm performing a regularization in the framework of the Lp Banach spaces. The capabilities of the method have been tested with noisy simulated data. The obtained results, although preliminary, confirm that the developed procedure is able to correctly retrieve the considered dielectric profiles.
