I am a novice trying ALOS PALSAR interferometry. at present I have two ALOS PALSAR 1.1 imagery downloaded from the Vertex website. I would like to create an interferogram using S1tbx. I tried the orthorectification of the imagery but following the deskewing method as given in the tutorials of ESA I have not been able to proceed with the interferometry process. Please help me!!
run ALOS Deskewing on both products first, followed by coregistration. Make sure the coregistration was correct by creating an RGB image of the coregistered pair. The third step is the generation of the interferogram.
Orthorectification should be the last step.
