As it is devoted to research investigations on radar polarimetry applied to land and vegetation remote sensing, it needs to be calibrated in phase and amplitude with a very good accuracy. A calibration procedure using trihedral and dihedral corner reflectors is presented here and then compared to the calibration method using random distributed targets that has been developed at the Jet Propulsion Laboratory. A very good agreement between both methods enables us to apply our calibration algorithms to natural surfaces measurements at different incidence angles (20°, 40° and 50°.
