Abstract

Polarization-selective dihedrals are developed for poalrimtric calibration of the PALSAR. The PALSAR is the first spaceborne polarimetric SAR boarded on the ALOS satellite launched in January 2006. This paper presents calibration experiments of PALSAR with the dihedrals in the ALOS initial calibration and validation phase. The reflectors are deployed in open fields of Tomakomai forest, to be imaged by not only the PALSAR but also the airborne polarimetric SAR, Pi-SAR.
