In the last years, the development of microwave imaging systems, aimed at reconstructing images of the dielectric properties of unknown targets from measures of the scattered field, has been a continuously pursued target. There are mainly two topics that must be faced. First of all, it is necessary to create fast and efficient measurement setups for obtaining the samples of the scattered electric field. Secondly, it is necessary to develop numerical methods able to extract from such measured values the needed information. In this paper, a multistatic measurement setup and an efficient reconstruction procedure are presented. Experimental results are provided in order to demonstrate the effectiveness of the proposed system.

Abstract
In the last years, the development of microwave imaging systems, aimed at reconstructing images of the dielectric properties of unknown targets from measures of the scattered field, has been a continuously pursued target. There are mainly two topics that must be faced. First of all, it is necessary to create fast and efficient measurement setups for obtaining the samples of the scattered electric field. Secondly, it is necessary to develop numerical methods able to extract from such measured values the needed information. In this paper, a multistatic measurement setup and an efficient reconstruction procedure are presented. Experimental results are provided in order to demonstrate the effectiveness of the proposed system.
