For the last few decades, microwave radiometers have played an important role in various remote sensing applications of the earth environment such as atmosphere, ocean and soil. Especially, various polarimetric emission for more accurate estimation. In general, the electromagnetic wave is represented as full Stoke parameters. The Stoke parameters can be defined as the horizontal and vertical polarization...
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...
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...
In this paper, we present the design and calibration of the fully polarimetric radiometer at 94 GHz. For stable and high sensible Stokes parameters measurements, we applied a wideband analog correlator and a total power type receiver with a periodic calibration. To perform the fully polarimetric calibration, a calibration standard was designed and tested. Using the calibration standard, the calibration...
