Hi everyone. I want to find fast ice displacement and I must use InSAR technique for that.
- As I saw in ESA advanced trainting course on remote sensing of cryosphere (second day) in this year to show how to derive Ice Velocity by processing a pair (12 days a part) of Sentinel-1 TOPS Extra Wide Swath (EW_GRDM_1SDH) images by using offset tracking technique.
I do not think so it can be useful for fast ice displacement because we do not use interferometry in this exercise. Am I right?
- I saw three tutorials about interferometry http://step.esa.int/main/doc/tutorials/sentinel-1-toolbox-tutorials/ :
Sentinel-1 Stripmap Interferometry
Sentinel-1 TOPSAR Interferometry
I think I must use ´Sentinel-1 TOPSAR Interferometry´ toturial and I must work with IW-SLC products. Am I right?
- As I understood, level 1 has 2 sides: GRD and SLC.
I think we can not use GRD for interferometry because Phase information is lost in GRD.
