Geocoding with PSI points

Hello, everyone.
I use S1TBX to preprocess Sentinel-1A images in SNAP. And then output to other SAR tool to do PSI and find the points.
After processing, I get PS points information with line, column and deformation. The next step, I want to geocode these points.
My idea is make pins for all the points and do the Range-Doppler terrain correction. However, this way is not work.
Please someone give me some advices, thanks.

Hi,

… output to other SAR tool to do PSI

sorry I can’t really answer your question, but which software do you use to do the PSI analysis? Isn’t there any option to do the geocoding?
Cheers,
