Sentinel-1A/B data are crucial for retrieving numerical information about surface phenomena and processes. Coregistration of terrain observation by progressive scans (TOPS) data is a critical step in its application. TOPS data must be fundamentally c

Burst Overlap Coregistration for Sentinel-1 TOPS DInSAR Ice Velocity Measurements

Autor: Anders Kusk, John Peter Merryman Boncori, Jonas Kvist Andersen

Publikováno v: Kusk, A, Andersen, J K & Boncori, J P M 2022, ' Burst Overlap Coregistration for Sentinel-1 TOPS DInSAR Ice Velocity Measurements ', IEEE Geoscience and Remote Sensing Letters, vol. 19, 4010905 . https://doi.org/10.1109/LGRS.2021.3062905

The application of Sentinel-1 interferometry to ice velocity measurements has until recently been limited by the significant horizontal scene motion associated with ice flow, which causes phase discontinuities (and associated unwrapping problems) at

Publikováno v: Acta Geodaetica et Cartographica Sinica, Vol 50, Iss 5, Pp 634-640 (2021)

TOPS mode is the default imaging mode of Sentinel-1 satellites, which requires an overall azimuth co-registration accuracy of 0.001 pixels to ensure that the interferometric phase difference of consecutive bursts is less than 3°. Although the ESD te
