Although there are a number of on-board calibration means not all necessary parameters are accessible. These parameters are subject to on-ground calibration and are not supposed to change from ground to orbit. The most important measurements to be done on ground are [:] the measurement of the diffuser BSDF [Bidirectional Scutter Distribution Function] for the wavelength range of interest [;] the characterisation of the polarisation response of the instrument as a function of the optical path (normal observation path and sun observation path), scan mirror position (the scan mirror reflectivity for S and P polarisation is a function of the mirror angle), and wavelength.

OBS

ground calibration: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
