Radiometric & Geometric Correction Workflow

Microwave Toolbox
35

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
