摘要：

The design method of calibration standard of fully polarimetric radiometer to measure the Stokes parameters at W-band is proposed. The information of 45 in a linear and a circular polarization are calibrated using the wire grid with thin Teflon substrate and the retardation plate which was implemented by dielectric plate with grove. The calibration standards show good performance on orthogonal channel polarization mixing (-17 to -25 dB), on mixing from the orthogonal channel into the polarimetric channels (-10.1 to -6.0 dB), and on mixing between polarization channels (-3.2 to -5.8 dB).
