No Sigma Naught Option for Radarsat2 Calibration

When I use the sentinel1 data , I have the option of “sigma naught” to save my calibration output; but surprisingly for the radarsat2 I have the option of sigma naught_db!

My radarsat 2 data SLC, Intensity > Multilooking> radiometric calibration> Filtering> Range Doppler Terrain Correction> converted to db at the end.

I’m having this same issue and wondering if its causing me problems later in processing.

I have noticed however that it could just be the default as it seems to automatically choose Sigma naught as the default.

Have you had any further progress on this? Anyone know more?


The default is sigma0
