Microwave 3D imaging of near-field scatterers mutually coupled with an antenna array

Abstract

In this study, we propose a three-dimensional (3D) imaging method for near-field scatterers that are mutually coupled with an antenna array, such as the support structure or fixtures of the antenna, based on bistatic microwave synthetic aperture imaging. This method can be used to evaluate the effectiveness of the antenna design with irremovable near-field scatterers. Numerical simulation and measurement results show the validity of the proposed imaging scheme.
