Abstract
The first part of this thesis considers the passive synthetic aperture moving target imaging problem using relatively wideband RF sources of opportunity such as DVB-T and WiMax signals. No knowledge of the transmitter locations or waveforms is assumed, so a correlation-based technique is used to backproject the data based on time difference of arrival between pairs of receivers. Velocity estimation is performed by forming images based on a range of hypothesized velocities, and analyzing the degree of focus of each image. We show that images with the correct hypothesized velocities will yield focused reconstructions of the corresponding moving target. In addition, a detailed performance analysis is developed for this method.
