Simultaneous Imaging of the Conductor and Dielectric Scatterer

This paper presents a new method to simultaneously image the perfect electric conductor (PEC) and dielectric scatterers together, which is based on the inversion algorithm subspace-based distorted-Born iterative method (S-DBIM). Simulation results show that method is able to distinguish the PEC and dielectric and can retrieve the relative permittivity for dielectric scatterer at the same time.
