Introduction to Radar data processing
Sensors
- PALSAR: Phased Array type L-band Synthetic Aperture Radar
- about system (HTML)
- ERSDAC PALSAR Pamphlet, PDF 8 pages
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
- 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: ...
