@lveci Thank you for quick response.
What confuses me is that you’re talking about Level0 products.
It seems that I succeeded - in case of SLC I have more bands, in case of GRDH, I receive two bands. Let me provide and example from SLC product:
Is “Radar --> Radiometric --> Calibrate” the only option which I need to apply to get backscatter for further calculations?
Should I apply also “Linear to/from dB” conversion?
