Hello guys!
I’m starting studying hard and processing S1 images and I would like to understand exactly what is the RTC processing, as done in this video:
Thanks!

Geometric terrain correction uses a DEM to correct the displacement of pixels because of the incidence angle of the imaging system. Foreshortening, shadow and layover.
Radiometric terrain correction uses a DEM to correct the backscatter intensity of pixels which are distorted by the local incidence angle.
Nice illustrations: http://www.geo.uzh.ch/microsite/rsl-documents/research/publications/other-sci-communications/2009_Small_1117-Pasadena-1544109568/2009_Small_1117-Pasadena.pdf
Thank you!
