This thesis presents the first systematic theoretical and experimental study of passive bistatic Synthetic Aperture Radar (SAR) imaging utilising Digital Television Broadcasting - Terrestrial (DVB-T) as an illuminator of opportunity. It presents the theoretical background for radar, SAR, and DVB-T transmissions, and studies the waveform on the basis of its ambiguity function. It considers the theoretical constraints of DVB-T SAR, including the impact of multiple transmitters and the properties of the DVB-T signal on image formation. It tracks the development and evolution of a receiver system and image formation algorithm, which is then validated through a series of ground-based and airborne experimental campaigns. From these campaigns, a catalogue of images are produced and analysed in order to establish the informational potential of DVB-T SAR imagery in both quasi-monostatic and bistatic environments. Specifically, the quality of images formed from a range of bistatic angles from 4 to 140 degrees is considered.
