Radiometric calibration or correction for SAR data?

what are the difference? In radiomeric correction process of SAR data, only beta,sigma or gamma calibration is applied or are there any other processes made?

This topic is already discussed ,

Intensity and coherence correlation

i looked up for old topics but i coulnt find direct and definitive answer about the differences even from some articles

Radiometric Calibration corrects each pixel’s value (backscatter intensity) according to several distortions (e.g. caused by incidence angle or sensor specifics)
Geometric correction corrects each pixel’s location according to slant range distortions and topographic influences.

Usually, both are required to make SAR data usable. But I agree with @falahfakhri that this forum is full of discussions on these two. If something is unclear, please ask more specificly.
