Some explanations about concepts of fringes of interferogram and coherence

Hello @dongiatti

I am happy I came across your work which was referred by @falahfakhri for one of my queries.
At the moment I am looking at some interferograms generated with S1 pair (Atmospheric Fringes) and I would like to clarify if the fringes are atmospheric or result of actual displacement. I would like to try out your method to mitigate the atmospheric elements if any.
