I have done a lot of tests to make the coregistration of these two images :
Radar -> Coregistration -> S1-TOPS Coregistration -> S1 TOPS Coregistration (with ESD) with different DEMs and resampling methods, always the same result : no slave image. That is mean the algo runs without error but when I open the slave image, I have an image with 0 everywhere.
Then, I take two other images :
Still the same result…
Thanks in advance.
Do you have an idea?
