Introduction to Radar data processing

Sensors

SAR analysis methods

  • SAR backscatter analysis (about): enables to estimate volume of water contained in soil, volume of biomass in forests, conditions of waves in the ocean etc.
    • Requirements: ...
  • SAR interferometry processing (about): enables to produce elevation data and to measure topographical change (two SAR images are used - called Master Image and Slave image, respectively)
    • Requirements: complex SAR data - Single Look Complex as parallax is not removed
    • General steps (cited from CCRS tutorial):
      • Process data to SLC images
      • Register the two images to 1/10 pixel
      • Over-sample by a factor of 2 in both dimensions
      • Filter common bands in spectrum
      • Conjugate multiply to form interferogram
      • Smooth the interferogram
      • Measure coherence
      • Unwrap phase
      • Estimate geometry parameters (especially baseline)
      • Remove flat-earth fringes
      • Convert unwrapped phase to height and/or motion
  • Polarimetric SAR processing (about): forest fire monitoring, classification of vegetation (height), water content in vegetation, monitoring of snow cover, condition of ice, flood monitoring and soil moisture.
    • Requirements: ...
