A generalized ART algorithm for inverse scattering problems related to buried cylindrical bodies

An inverse scattering problem whose aim is to recover the electromagnetic properties of buried cylindrical bodies is addressed. The problem is first reduced to a system of operator equations and then its solution is obtained through an iterative method which is a generalization of the algebraic reconstruction technique in diffraction tomography to the present problem. The use of such an iterative method enables us to find a unique solution with a small number of measurements. Some illustrative examples show the accuracy and the applicability of the method.
