Error during interferogram formation


#1

Hello . i am working with sentinel 1 data for deformation analysis. Once i processed the interferogram i am getting no data in the window. I have attached the sample img with this. can someone tell me what the problem is.

how does the coregistered stack look? You can check if coregistration was successful by making an RGB image out of your bands.


#3

It looks like a problem in the coregistration process

Check if the slave image in your stack file has correctly been coregistered

Additionally, your temporal baseline seems to be 492 days which is extremely long for interferometric applications.

As suggested by qglaude, coregistration was probably not successful.
As you are in mountainous areas, you can try the DEM-assisted coregistration which is often more suitable in pronounced topographies.

thank you… will check the error…!!!
