Data Set Abstract AIRSAR is the Jet Propulsion Laboratory's airborne polarimetric SAR that operates at C (5.66 cm), L (23.98 cm), and P (68.13 cm) wavelengths in a polarimetric mode (Zebker et al., 1987). AIRSAR acquires data that can be processed to backscatter image formats with range and azimuth resolutions of approximately 20 meters. The pixel values are expressed in radar backscatter cross section as 32-bit numbers. The cross section is the area of a half sphere that would scatter the amount of power received by the antenna.
