Abstract

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 the effects of platform motion during reception and develop an exact solution to compensate for Doppler. A pseudorandom (PN) binary phase-coded waveform is used to represent the digital, high definition television waveform and justified based upon measured signal examples.
