Sentinel1 callibration procedure

[jmpark1]

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

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)…

Export

3D Plot and pixel information

If you want to plot the phase data in matlab, export the phase raster to GeoTiff.
