Glacier monitoring using frequency domain offset tracking applied to sentinel-1 images: A product performance comparison
The Sentinel-1 mission has now reached its maturity, and is acquiring high-quality images with a high revisit time, allowing for eective continuous monitoring of our rapidly changing planet. The purpose of this work is to assess the performance of the dierent synthetic aperture radar products made a...

The Sentinel-1 mission has now reached its maturity, and is acquiring high-quality images with a high revisit time, allowing for eective continuous monitoring of our rapidly changing planet. The purpose of this work is to assess the performance of the dierent synthetic aperture radar products made available by the European Space Agency through the Sentinels Data Hub against glacier displacement monitoring with oset tracking methodology. In particular, four classes of products have been tested: the medium resolution ground range detected, the high-resolution ground range detected, acquired in both interferometric wide and extra-wide swath, and the single look complex. The first are detected pre-processed images with about 40, 25, and 10-m pixel spacing, respectively. The last category, the most commonly adopted for the application at issue, represents the standard coherent synthetic aperture radar product, delivered in unprocessed focused complex format with pixel spacing ranging from 14 to 20 m in azimuth and from approximately 2 to 6 m in range, depending on the acquisition area and mode.
