Microwave Imaging Through a Mode-Matching Bessel Functions Procedure

A novel imaging procedure based on ultra-wideband microwave signals is presented. The procedure exploits the use of Bessel functions mode-matching approach for the identification of the presence and location of significant scatterers inside cylindrically shaped objects. Simulations and measurements on cylinders with inclusions are provided to show the capability of the procedure for capturing the contrast due to different material properties, and this is achieved through the generation/inversion of relatively small matrices. An example involving multilayered cylindrical objects approximating humanlike tissues containing an inclusion is also presented.
