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.
