I need the steps applied to create the interferogram in SNAP 6.0 and the phase developed in SNAPHU
these are the steps:
Step 1. Open data
Step 2. Corregistration
Step 3. Interferogram formation
Step 4. Tops derbust
Step 5. Topographic phase removal (DinSAR)
Step 6. Goldstein phase filtering
Step 7. Multilooking
Step 8. Snaphu export
Step 9. Unwrapping phase with SNAPHU
Step 10. Import unwrapping with SNAP
Step 11. Unwrapped phase result
Step 12. Phase conversion in displacement
Step 13. Range doppler terrain correction
Step 14. The file obtained is exported as a tiff for procesing in QGIS 3.10
From the steps applied i ask for your opinion and the answer according to your experience for the following questions:
a). If the water does not discriminate in the interferogram, how do you eliminate the effect of coherence in slow waters?
b). If the band can identify areas identified by the potential for water erosion and wind erosion in areas without vegetation cover?
c). If the interval time of 1 year can be taken as a reference for surface deformation or subsidence?
