Abstract

Staggered SAR is an innovative synthetic aperture radar (SAR) concept, where the pulse repetition interval (PRI) is continuously varied. This, together with digital beamforming (DBF) in elevation, allows high-resolution imag-ing of a wide continuous swath without the need for a long antenna with multiple apertures. Criteria for the de-sign of sequences of PRIs and data processing strategies are presented, together with some system design con-siderations. The impact of staggered-SAR operation on image quality is furthermore assessed, using highly over-sampled F-SAR airborne data and operating TerraSAR-X in staggered-SAR mode.
