A New Modality for Microwave Tomographic Imaging: Transit Time Tomography

Buford Randall Jean, Matthew L. Trumbo, Robert J. Marks II

Abstract


A method is presented for tomographic imaging using time delay of broad band microwave signals passing through objects of varying electrical properties. Time delay imaging is mathematically equivalent to that of conventional planar X-ray tomography. The experimental setup for transit time tomography consists of a circular table with vertically polarized bi-conic horns as transmitting and receiving antennas. A vector network analyzer serves as the excitation and measurement device. By obtaining multiple time delay tomographic projections at multiple angles, a reconstruction of a cross section of the image can be obtained. Experimental results are presented for several targets.
