Polarimetric calibration of PI-SAR2: Experimental results of 2013 to 2015 observations

An X-band airborne SAR, Pi-SAR2, has been developed by NICT. It can make polarimetric and interferometric observation with very high spatial resolution of 0.3m. Since 2013, NICT has carried out collaborating observations on research proposals selected for the Pi-SAR2 Research Announcement. Polarimetric SAR data analysis is a key issue among them, therefore we have made polarimetric calibration in each observation period.
