Unable to read the RADARSAT data

SNAP not allowing to read a zip file of RADARSAT data. How to read it and do calbiration of RADARSAT data in SNAP using s1 tbx ? does SNAP support RADARSAT data ?
radar

have you tried it like this and selecting the 001 file inside (after extraction of the zip file)?

Actually, my SNAP is not showing “RADARSAT” option in File>Import>SAR Sensors>

Why is it so ?

I’d suggest to go to the download page and select “all toolboxes“ and install again.

No. I just downloaded S1tbx. I never used S2tbx

what version are you using?

s1tbx 6.0.6 and snap 6.0.10
