Abstract :
A new polarimetric calibration method is proposed based in the scattering matrix decomposition, via Pauli matrices, which works with target spinor instead of the scattering matrix. The base elements of target spinor are the target spinor corresponding to the usual calibrators like sphere, dihedral and 45° rotated dehedral. This fact allows the error coefficients to be calculated by a direct and easy way. This paper shows experimental results obtained from measurements of a metallic sphere carried out in a compact range using TSC (target spinor calibration)
