A new polarimetric calibration method is proposed based on scattering matrix decomposition, via Pauli matrices. This scheme operates with the Pauli target vectors instead of the scattering matrix. The base elements of the Pauli target vectors are the vectors corresponding to the usual calibrators such as sphere, dihedral and 45° rotated dihedral. This fact allows direct and easy calculation of the error coefficients. An experimental validation of this method is presented.
