So I’m working through an ESA Interferometry tutorial and although it seems I am following all of the steps properly, my interferogram does not resemble the one in the tutorial, but my coherence map looks fine. When I attempt to work forward, my final phase unwrapped result becomes a continuous vertical gradient. What have I done wrong?
I used the data provided by the tutorial. I did not apply multi-looking to the dataset. Should that be done after the co registration but before the interferogram formation?
So I ran multilooking on the interferogram with various inputs. The results are smoother, but they still do not properly match what is shown in the tutorial.
not really. You can test if the coregistration was successful by creating an RGB composite of the intensities of both dates. If they match correctly, the inteferogram is also correct. I have no idea why yours is different from the tutorial then…
So I made the composite, and they seem to line up nicely, but there is a section at the bottom of the image that is just red. Could this somehow be resulting in my issues?
