Three-Dimensional Far-Field Holographic Microwave Imaging: An Experimental Investigation of Dielectric Object
TLDR
In this paper, a 3D far-field holographic microwave imaging (HMI) method for diagnosing inclusions within dielectric objects is presented, which relates to electromagnetic imaging to reconstruct dielectrics properties of inhomogeneous, lossy bodies with arbitrary shape.Abstract:Â
This work presents experimental investigations of three-dimensional (3-D) far-field holographic microwave imaging (HMI) method for diagnosing inclusions within dielectric objects, and in particular, it relates to electromagnetic imaging to reconstruct dielectric properties of inhomogeneous, lossy bodies with arbitrary shape. The apparatus is designed for operation at a single frequency of 12.6 GHz. 16 antennas are located on a 2-D array plane which is placed under the object in the far-field region, with air in the space between the antenna array and the object. Experimental results indicate that the 3-D HMI system has the ability to produce a 3-D image of multimedia dielectric object and detect small inclusions embedded within an object. The invention has potential application to tissue imaging.read more
