To network cognitive radios that require spectrum sensing to identify transmission opportunities emerges as a critical technology to facilitate spectrum efficient wireless communi...
The autofocus problem in synthetic aperture radar (SAR) is considered, where phase errors in the acquired signal data result in imagery that is improperly focused. We present a ne...
Optical coherence tomography (OCT) is an optical ranging technique analogous to radar — detection of back-scattered light produces a signal that is temporally localized at times...

We introduce a new bistatic synthetic-aperture imaging method for a radar system consisting of two receivers, which will be referred to as hitchhikers, and a source of opportunity...
We introduce a novel synthetic-aperture imaging method for radar systems that rely on sources of opportunity. We consider receivers that fly along arbitrary, but known, flight traj...
