Phase problem (single purple color) in interferometric processing chain

[falahfakhri]

Could you please suggest some tutorial that will guide me with all the necessary steps after these :

Please take a look at this tutorial video,

Also my area of interest lies in IW2 and IW3. What would be the easiest way to proceed in order to study the deformation in the whole area?

You could apply TOPSAR-Merge for merging subswaths (IW2 and IW3),

Thank you so much @falahfakhri
I have followed (coreg–>ifg–>deburst–>topophase–>goldstein filt–>snaphu export) till now.
I will try to follow the suggested tutorial.
Also, TOPSAR-merge is to be done at which step?

(coreg–>ifg–>deburst–>topophase–>goldstein filt–>s

Apply orbit is missing!

Also, TOPSAR-merge is to be done at which step?

I explained in the following post,

This one way, the other way you could try up is,

For each single Subswath,

Split ------->apply orbit------->deburst

Topsar merge of both IW2 and IW3 ------->corr. , and continue your processing, IF this approach doesn’t assist your demand move to the first one,
