I am using the most recent version of the Sentinel-1 toolbox and am processing Sentinel-1A interferograms by following exactly the steps in the manual http://sentinel1.s3.amazonaws.com/docs/S1TBX%20TOPSAR%20Interferometry%20with%20Sentinel-1%20Tutorial.pdf
So far I have processed 3 or 4 interferograms, which have worked fine. However, for these scenes:
there are offsets between the bursts that I am having trouble removing (see figure). Looking through the manual and the forum I can’t really find a clear explanation of how to remove these.
I have coregistered the two scenes using the “S1 TOPS coregistration” option. I have then selected to use the “S-1 Range Shift” and “S-1 Azimuth Shift” steps before resuming the steps in the manual (interferogram formation, deburst etc). Is this the correct place to do these steps? I have found that using them is making no difference to my results.
Any advice would be appreciated.
