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...
Many parameters are required for the measurement of the sea surface currents and the sea levels simultaneously by the along-track interferometry SAR (AT-InSAR). To estimate the elevation or the sea levels from the signals observed by the AT-InSAR, the method for synthesizing these received signals was developed. To evaluate the estimation method, the ground surface was observed by the cross-track...
In the National Institute of Information and Communications Technology, Japan (NICT), we have developed an advanced X-band airborne synthetic aperture radar (SAR) system, Pi-SAR2, since 2006, to succeed the X-band polarimetirc and interferometric airborne SAR, Pi-SAR. The Pi-SAR2 has a higher spatial resolution of 0.3–0.6 m in the azimuth direction and 0.3–0.5 m in the range direction, as well as...
