Terrain Correction in SNAP vs Geocoding PolSARpro

Hello Everyone.

I would like to know SNAP Terrain correction tool and PolSARpro Geocoding tool are using the same algorithm or not? I applied Terrain correction using SNAP and geocode my image using PolSARpro but results are different. It makes me confuse because PolSARpro is using s1tbx for geocoding. I will be thankful if someone kindly answers my query.


could you maybe provide screenshots of the terrain correction outcomes of both programs?
If PolSARpro points to the same SNAP version you are sing the results should be the same.
