Radiometric & Geometric Correction Workflow

[ABraun]

for SLC data I would suggest

1. TOPS Split
2. Apply Orbit file
3. Thermal Noise Removal
4. Calibration to Beta0*
5. TOPSAR Deburst
6. Radiometric terrain flattening
7. (Speckle filtering)
8. 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. Apply Orbit file
2. Thermal noise removal
3. Calibration to Beta0
4. Radiometric terrain flattening
5. (Speckle filtering)
6. Range Doppler Terrain Correction

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

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