Abstract
An improved calibration method for a wideband polarimetric measurement system using three partly unknown, perfectly polarization-isolated calibrators is presented, with experimental results measured from 7 to 17 GHz. The cross-polarized information is provided by rotating the third calibrator to an arbitrary angle with respect to the radar range direction. Only the copolarization terms in the polarimetric scattering matrix (PSM) of the first calibrator are required to be specified. The copolarized scattering properties, including the range information of the other two calibrators and the rotation angle of the third calibrator, can be acquired in the calibration process and used to verify the calibration accuracy.>
