Abstract :
A novel PARC of Van Atta array design is developed for polarimetric calibration of PALSAR onboard the ALOS satellite. The PARC consists of four dual-polaraized 3×3-cross-dipole subarrays. The Van Atta array configuration combining with dual-polarized nature of the subarrays provides the PARC the depolarizing and retrodirective characteristics simultaneously.
