N2 - While traditionally employed in acoustics, tomographic imaging techniques have made a transition into the microwave regime and are finding application in areas such as ground penetrating radar (GPR). While excitation methods vary depending upon the application, little or no literature exists on the use of an arbitrary noise waveform as an excitation method in tomography. This paper complements the existing literature on tomography by presenting an ultra wideband (UWB) radar design, utilized for tomography, whose excitation source is of an arbitrary noise origin operating from 4 to 8 GHz at a full 4 GHz bandwidth. Evidence of this source's ability to be used in tomography is presented through the generation of two dimensional cross sectional images of three dimensional objects such as metallic and dielectric cylinders in various positions, under both unobscured and concealed conditions.
