The application of three-dimensional tomographic imaging using nontraditional emitters and waveforms has previously been explored. In analytical studies the imaging potential of bistatic hitchhiking using digital television emissions with an airborne receiver has been quantified against idealized scatterers. The processing associated with the noise-like waveform, mitigation of direct signal breakthrough...
We continue the evaluation of nontraditional emitters and waveforms to bistatic radio frequency tomography using digital broadcast television signals, and the associated waveform processing. This paper is a sequel to the original work wherein the move-stop-move approximation was employed and the problems of direct signal breakthrough were covered. Here we evaluate tomographic reconstruction including...
Image reconstruction using tomography is based on inverse filtering a series of projections, collected at angular positions surrounding an object or scene, where the form of the projection is derived from the measurement geometry (monostatic/bistatic, point/plane transducer/sensor) as well as the probing phenomenology. We expand the application of tomography to nontraditional emitters and waveforms...
There are multiple applications that would benefit from the ability to produce three dimensional, high resolution, imagery collected at low operating frequency; among them remote archeological survey of ruins through foliage, and searching for voids in collapsed structures and underground. High vertical resolution circular SAR requires the use of wide-to-ultra wideband waveforms, a problematic aspect...
