Full dual polarization W-band scanning radiometer and stokes parameter measurement

The W-band fully polarized radiometer with the detail calibration is presented. The calibration standard for the measurement of Stokes parameters was designed and the measured results are presented. For the calibration standard, a wideband analog correlator was designed and described the performance. The correlation coefficient of the U and V Stokes parameter was 0.92 and 0.96, respectively. The detail analysis of the error of the calibration is presented in terms of random and systematic uncertainty.
