The active technique of microwave imaging has recently proven to provide excellent diagnostic capabilities in several areas. Offering comprehensive descriptions of the most important techniques so far proposed for short-range microwave imaging (including reconstruction procedures, imaging systems and apparatuses, and current applications), Microwave Imaging includes a review of the inverse scattering problem formulation written from an engineering perspective and notations. This comprehensive text provides scientists and engineers with an introduction to the most relevant theoretical and algorithmic aspects of modern microwave imaging approaches,
