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. S1A_IW_GRDH_1SDV_20160912T035113_20160912T035136_013014_0149C4_6E2F S1A_IW_SLC__1SDV_20160912T035112_20160912T035136_013014_0149C4_CF51 I wanted to see the change in the result if different input data and modules are applied. These…

Correct SAR calibration steps

Hello Giacomo, The SAR processing -> radiometric -> calibrate process converts the pixel data to actual backscattering values. It should be performed first in whatever processing chain you do. If you need to do polarimetric work after with your data, you need to check the box marked «Save in complex» when calibrating. After this step, your image has backscattering intensity pixels and is in ground range or slant range geometry. The SAR processing -> Geometry -> Terrain correction -> Range Dopp…
