A real-time microwave imaging of unknown anomaly with and without diagonal elements of scattering matrix

Abstract

In this contribution, a real-time non-iterative microwave imaging of unknown anomaly from scattering matrix whose elements are scattering parameters measured at the dipole antennas considered. For this, we apply Kirchhoff migration imaging technique when the diagonal elements of scattering matrix are available or unavailable, and confirm that opposite to the traditional researches, one can obtain good result without diagonal elements. Simulation results with synthetic data are presented to support our confirmation.
