ROSE-L SAR Instrument Design Overview and Performance

Abstract:
The ROSE-L SAR Instrument is the radar payload of the ESA Copernicus Expansion Programme ROSE-L mission, which will complement the already operational Copernicus C-band Sentinel-1 SAR mission by adding an L-band high resolution and wide swath synthetic aperture radar imaging capability. The paper presents an overview on the ROSE-L SAR Instrument design, its Digital Beamforming implementation as well its SAR Mode design and the corresponding SAR performance prediction.
