S1 bit-depth

Although ERS-1/2 SAR were simplier, their calibration was still quite involved especally while trying to understand the impact of the ADC - the document CAL01.pdf is from 1993! Although it seems the S1 calibration is more complicated, there is now a lot more information in the product annotation and documention to enable anyone, after some time, to perform calibration. After all there was not a tool like SNAP back in 1991.

Hi, Can someone still explain to me in simple terms how you get >100% of the emitted signal reflected back so that sigma >1.0?

Thanks

as @mengdahl wrote above, this is not the correct reason why Sigma0 can be >1.

OK, got it. Thanks ABraun for helping me to understand.

All the best.
