The Staggered SAR concept: Imaging a wide continuous swath with high resolution [PDF]

, 2013
Staggered SAR is an innovative synthetic aperture radar (SAR) concept, based on the continuous variation of the pulse repetition interval (PRI). This concept allows high-resolution imaging of a wide continuous swath without the need for a long antenna ...

Sparse Aperture Inverse Synthetic Aperture Radar Imaging for Maneuvering Targets With Migration Through Resolution Cells Correction

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Due to the nonstationarity of the echo, it is hard to form a well-focused sparse aperture inverse synthetic aperture radar (SA-ISAR) image for maneuvering targets by traditional algorithms.
