Due to the many advantages of passive radar and ubiquity of commercial broadcast transmitters, interest in passive bistatic radar (PBR) applications has continued to grow. More specifically, sources studying commercial orthogonal frequency division multiplexing (OFDM) waveforms for passive bistatic synthetic aperture radar (SAR) imaging have become more common. This work evaluates and applies long term evolution (LTE), digital video broadcast (DVB), and digital audio broadcast (DAB) signals of opportunity for passive bistatic SAR imaging.
First, implications of the structure and properties of each of the signal of opportunity's transmitted waveform are characterized by examining the waveform's self- and cross-ambiguity functions (AFs). In addition to deriving waveform properties, link budget analysis is completed using pessimistic values intrinsic to LTE, DVB, and DAB transmissions for predicting performance of potential passive bistatic SAR imaging scenarios. Small-scale, passive bistatic SAR imaging experiments are carried out using signals structured similarly to LTE, DVB, and DAB signals, demonstrating the merits of the considered processing schemes for passive bistatic SAR image generation.
