ASAR backscatter

Hi! Could someone confirm the processing steps/chain in order to go from ENVISAT ASAR IMP mode to backscatter, and ENVISAT ASAR IMS mode to backscatter, using the SNAP Toolbox?


You should only need to calibrate to Sigma0 for both.

Thanks Iveci! Do I need to, however, go through terrain correction + speckle filtering?

You need to terrain correct if you need the true geographic coordinate of the pixels. I would do this after other SAR processing and just before needing to compare the data with something else like a shape file or other images.
