S1 Pre-processing chain and parameter setting

[ABraun]

slope normalization is needed because the signal strongly varies according to the angle which it hits a surface:

You can also automatically do it in SNAP by calibrating to Beta Naught and then apply the Radiometric Terrain Correction. I made some comparisons here:

S1 radiometric correction

I did a few tests because I still wonder about the best pre-processing parameters for Sentinel-1. I therefore downloaded a Scene from 12.09.2016 which covers Cyprus (GRD and SLC). I chose this area due to its topographic complexity and the little vegetation cover.
