How Decompose Sentinel-1 GRDH data

do you have SNAP-S1TBX manual?
i am a fresh user of snap also would you like to help me how to access sentinel-1 data until processing till get to be interferogram?
i need some tutorial in it.
thnk you

These might me what you seearch for:

Especially the interferometry ones.

25

yes thanks,
ohya, is it same or not. i installed snap software but is it same as s1tbx software?

26

SNAP consists of various toolboxes, the S1TBX for radar data, S2TBX for optical and so onā€¦ It used to be named just S1-Toolbox but since the release of SNAP all are bundled in one large software package.

how to make interferogram D-InSAR ? (using SNAP)

There are any files like this tutorial regarding the processing of GRD and SLC data ?

please have a look here:

Kindly explain
What are the other decomposition method can apply in dual pol data (Sentinel-1) except H-Alpha dual pol decomposition? Can I apply Freeman or Yamaguchi decomposition in dual pol data?

32

no, they rely on fully-polarized data (HH/HV/VH/VV). With Sentinel-1 data you can only use the ā€œdual-polā€ decompositions.

33

Thank you so much for your reply.
That means only H-alpha dual pol decomposition can be applied in sentinel data not others.

34

or ALOS (HH/HV), ENVISAT co-pol (HH/VV) and other dual-polarized SAR sensors.

Hi
@ABraun Iā€™m working on soil moisture problem.I want to have decomposition information from sentinel-1 data for regression issues. Do you mean that i couldnā€™t use GRD format for decomposition and itā€™s wrong if I do decomposition on GRD format?
Could you please tell me whatā€™s the processing step if i could use GRD format?
thanks in advance

yes, you need SLC data for polarimetric analysis. A general tutorial on polarimetry with quad-pol data is provided here: SAR Polarimetry and Analyses

This one addresses Sentinel-1 processing (dual-pol) in particular: https://www.preprints.org/manuscript/201911.0393/v1
