Interferometric investigations with the Sentinel-1 constellation
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017 The contribution focuses on the current status of the ESA study entitled “InSARAP Sentinel-1 Constellation Study”, which investigates the interferometric performance of the S1A/S1B units. General aspects like the interferometric compatibility in terms of common range and Doppler bandwidth and the burst synchronization are addressed.

Sentinel-1 Support in the GAMMA Software [PDF]
Procedia Computer Science, 2015 AbstractFirst results using the new Sentinel-1 SAR look very promising but the special interferometric wide-swath data acquired in the TOPS mode makes InSAR processing more challenging than for normal stripmap mode data. The steep azimuth spectra ramp in each burst results in very stringent co-registration requirements.

Canonical Analysis of Sentinel-1 Radar and Sentinel-2 Optical Data [PDF]
, 2017 This paper gives results from joint analyses of dual polarimety synthetic aperture radar data from the Sentinel-1 mission and optical data from the Sentinel-2 mission. The analyses are carried out by means of traditional canonical correlation analysis (CCA) and canonical information analysis (CIA).
