Mosaic of SAR Subswaths for DInSAR Analysis

2023-09-21T19:00:00Z

Hi, I am new to SAR interferometry. I’d like to confirm whether my process flow for mapping earthquake activity using the DInSAR technique is correct or not. As the Earthquake activity lies in the middle of both subswaths, I merged them and followed DInSAR.

Here is the process flow:
S1-TOPs Coregistration > Interferogram formation > Debursting > S1-TOPs Merge> Topographic Phase Removal > Multilooking > Goldstein Phase Filtering > Snaphu_Unwrapping > Phase to Displacement

Before merging subswaths, I have separately followed the steps of Coregistration , interferogram and debursting for IW1 and IW2.

Here is the result after Goldstein Phase Filtering:
