Sentinel1 callibration procedure

I’m pretty new to the sentinel1 datasets.

I downloaded s1A_IW_GRDH datasets to obtain the backscatter coefficient.

I knew that i can calculate sigma at the radiometric calibration

But im still curious about what kind of calibration need to be applied.

Thermal noise removal/ Speckle filtering/ Ellipsoid correction/ Range-Doppler terrain correction?

Additionally, can i open file which finished calibration procedures at matlab? I had difficulty in making mesh grid in matlab… because only limited lat and long is provided and it is not rectangular form

maybe this helps you:

Radiometric correction
