I understand that SAR processing is best in areas with high coherence. I have 3 questions:
In SNAP, which step should the mask be applied in? Is it right after coherence map generation?
When it comes to masking, do i simply use something like:
if (coherence >= 0.6) then 1 else NaN ? Is 0.6 a good threshold or is it too strict?
- For unwrapping in the masked areas, is the result of the unwrapped phase also ‘NaN’ for masked areas?
