The PS calibration combines external devices, like corner reflectors, transponders and the stable targets to provide continuous monitoring of the radiometric quality of a SAR instrument. The aim is to provide, on the bases of image blocks (say 10 x 10 km), the precise geolocation and the polarimetric signature of each scatterer. The scheme thus requires (1) the identification of the stable targets, and (2) the characterization of their Polarimetric scattering matrix by external references. In that way, it would be possible to calibrate even a dual polarimetric system.

Abstract

The PS calibration combines external devices, like corner reflectors, transponders and the stable targets to provide continuous monitoring of the radiometric quality of a SAR instrument. The aim is to provide, on the bases of image blocks (say 10 x 10 km), the precise geolocation and the polarimetric signature of each scatterer. The scheme thus requires (1) the identification of the stable targets, and (2) the characterization of their Polarimetric scattering matrix by external references. In that way, it would be possible to calibrate even a dual polarimetric system.
