These are my steps.
select two SLC images and open in SNAP.
creat Subset
Coregistration
Interferogram generation
Topsar Debrust
Topographic Phase Removal
Multilooking
Goldstein Phase Filtering
then the number (8)
snaphu export
snaphu import(no 9)
and create no 12 by Range Doppler Terrain Correction ( picture also there), ( no.10 also same but I try to add the unwarp phase band and others together in single file.)
After this,
I try to run Phase to height, but in this, a new file is created but there is no band.
I hope you got my mistakes.
After that,
i tried to make phase displacement and got it like this.
may i need to take three images for generating Interferogram, to get DEM?
Hopping your comments.
