Extract the backscatter coefficient value

@ABraun

for SLC data I would suggest

1. Calibration to Beta0
2. TOPSAR Deburst
3. Apply Orbit file
4. (Speckle filtering)
5. Radiometric terrain flattening
6. 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:

1. Thermal noise removal
2. Apply Orbit file
3. Calibration to Beta0
4. (Speckle filtering)
5. Radiometric terrain flattening
6. Range Doppler Terrain Correction

or (if you don’t have much topography):

1. Thermal noise removal
2. Apply Orbit file
3. Calibration to Sigma0
4. (Speckle filtering)
5. Range Doppler Terrain Correction

You make a graph of this chain. Then you use it in batch processing
