I have been reviewing the literature on SBAS and I’m having difficulty in determining a “sweet spot” for temporal baseline between pairs for SBAS analysis.
Studies are using ranges from less than 50 days to 250 days and over (!) between pairs using Sentinel-1, without really explaining the reasoning behind choosing that specific number.
What is your experience with SBAS and temporal baselines? I am currently allowing for a max of 48 days between pairs but even with such a small baseline I am reaching hundreds of IFG’s for very long study periods, anything higher would create an unreasonable processing time.
