In fringe 2017 someone commented about a bug in 3 pass differential interferogram which made the tool unreliable. But also they commented that having DEM for almost every part of the world the results of a 3-pass interferogram is going to be worse than if you use DEM to generate the topographic phase. Is your study zone a polar zone without DEM coverage?
