When I import ALOS PALSAR 1.1 level product into SNAP, I think q and i are the SLC values, but I also import it into POLSARpro and I can only generate the S matrix, Shh, Shv, Svv , but they are not SLC values. And why the C3 matrix generated by SNAP is not the same value as the C3 matrix generated by PLOSARpro?
