dc.description.abstract A new method for tomographic imaging using time delay of microwaves as they pass through objects of varying dielectric is presented. To obtain this delay measurement, recording of transmitted waveforms is performed when broadband microwave signals are sent through objects. The experimental setup consists of a circular table with vertically polarized bi-conic horns as transmitting and receiving antennas, with a Vector Network Analyzer as the excitation and measurement device. By obtaining multiple point tomographic projections at multiple angles, a reconstruction of the classic X-ray Radon transform is possible. Results obtained show accuracy and resolution limits to be within acceptable ranges and offer many new, less expensive possibilities for tomographic imaging. en
