Tomography using digital broadcast television

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 through the use of digital broadcast television signals, and the associated waveform processing, in place of the more traditional pulsed or CW waveforms. This paper evaluates reconstruction based on a three dimensional aperture, employing a pseudorandom (PN) binary phase-coded waveform to represent the digital, high definition, TV emitter.
