How to prepare Sentinel-1 images stack for PSI/SBAS in SNAP

Pardon my little knowledge but I thought the areas lying at the overlap between two acquisitions are prone to produce undesirable range Doppler centroid frequency error that contributes to the total Interferometric phase, that’s why I was only attempting to work on images that are acquired at the exact same frame (even though some images may not be perfectly lined up within a single frame) .

No need to apologize. Many studies combine images of S1A and S1B or acquisitions from different frames. We talked about the effect on baselines here and it shouldn’t matter: S1A-S1B coherence of partially overlapping images - #16 by mengdahl
