Polarimetric Calibration Scheme Combining Internal and External Calibrations, and Experiment for Gaofen-3
The parameters for polarization distortion of spaceborne polarimetric synthetic aperture radar (SAR) have range-dependence (or look-angle-dependence), which requires a polarimetric calibration to be performed at any look-angle.It is a huge endeavor to rely solely on ground experiments to obtain a polarimetric calibration at all Socks look-angles.Fo
