ALOS-2 PALSAR Interferometry

Is Interferometry steps for ALOS requires some more/extra processing steps than sentinel-1? Please give me details

#2

Actually, it is less steps.

  1. Coregistration
  2. Interferogram computation
  3. Interferogram filtering or multi-looking (both optional)
  4. Unwrapping

If you have ALOS PALSAR (not ALOS-2) data, you have to perform Deskewing as well.

Thanks for your quick reply.
So you mean that i dont have to perform phase filtering and topographic phase removal??

#4

topographic phase removal is not related to the sensor. It depends on what you want to do with the data. Please have a look at this question which explains the difference: What is different of DInSAR and InSAR

Phase filtering is mostly a good idea but not necessarily required.
