Abstract :
Microwave imaging apparatuses have become very important tools in the framework of imaging systems. However, particular care must be used when developing the data processing algorithm needed to solve the underlying nonlinear and ill-posed inverse problem. Usually, regularization techniques developed in the framework of Hilbert spaces are used. In this paper, a new approach, based on a regularization in the framework of Lp Banach spaces is considered and its performances are evaluated by considering a reference canonical target with elliptical cross section.
