SAR Images pre-processing (Sentinel-1) in the SNAP

Undoubtedly, There are errors & distortions on the satellite images that are inevitable at some points such as sensor sensitivity, atmospheric effects, positional errors, displacements, and so on. the mentioned error and distortions should be corrected to reduce their effects on our processing, for this purpose we use Radiometric and Geometric corrections to correct the distortions and errors. these corrections may not eliminate the errors but significantly reduce their effects. in this video, we apply a few Radiometric and Geometric corrections on Sentinel images that are more essential such as calibration, Radiometric Terrain Flattening, Thermal Noise Removal, Range-Doppler Terrain Correction. We also show you applying these corrections with different methods and show you how to work with Graph Builder which helps you to apply all the corrections at once. if you have any questions, you can ask in the comment section.
