Problems with the Range Doppler Terrain Correction tool

[Asthar]

Thank you all for your answers, however I found the solution not in the FAQ, but in the link and process that I detail below, for which I am very grateful to Andreas Braun from Germany (ABraun) for providing these instructions and others

Radiometric & Geometric Correction Workflow

for SLC data I would suggest TOPS Split Apply Orbit file Thermal Noise Removal Calibration to Beta0* TOPSAR Deburst Radiometric terrain flattening (Speckle filtering) Range Doppler Terrain Correction If you don’t need the phase information you can also download it as a GRD product and only apply the following: Apply Orbit file Thermal noise removal Calibration to Beta0 Radiometric terrain flattening (Speckle filtering) Range Doppler Terrain Correction or (if you don’t have much topography)…
