摘要：NICT (National Institute of Information and Communications Technology, Japan) has developed an X-band high performance airborne SAR system (Pi-SAR2) since 2006, as a successor to the Pi-SAR (X-band). Pi-SAR2 system is installed to the Gulfstream II business jet. Pi-SAR2 has polarimetric and interferometric functions with high spatial resolution of 0.3-0.6 m in along track (azimuth) direction and 0.3-0.5 m in cross track (slant-range) direction. In this paper we report the ground based calibration experiments using corner reflectors (CR) in conjunction with the Pi-SAR2 test flights. The calibration experiments were carried out at the runway of the Taiki aerospace experiment field in Hokkaido, Japan in December 1-2, 2008 and February 2, 2010. We also report the backscattering characteristics of snow cover on the runway of the X-band high-resolution SAR image
