Whether it is possible to use radar images of “Sentinel 1” for to solve correctly following problem: To measure seasonal change of height of a surface of a glacier about several meters.
Conditions following: ice constantly moves with a speed about 0,2 m/day, the surface is covered with stone fragments, time period is possible when ice is “dry” has no water on a surface.
It is known that DEM on “Sentinel 1” has a mistake on height of 20-30 m.
Differential interferogram ???
Yes, you could use the TOPS mode S1 GRD products (offset tracking )
I don’t think this will be possible - even if the glacier did not move it would be difficult to impossible. With moving glaciers the problem gets more complicated still, since movement in the range-direction generates a lot of extra fringes on the interferograms…
