Abstract :
A novel approach to calibrate a polarimetric SAR is proposed and tested in the SIR-C/X-SAR experiment. The present technique needs one PARC (polarimetric active radar calibrator) and two PSDs (polarization selective dihedrals). Since PSDs have wide frequency coverage, only addition of another frequency PARC allows to calibrate a multi-frequency polarimetric SAR
