Abstract :
The HUT 36.5 GHz polarimetric radiometer is described. It is modified from a conventional two-channel radiometer, and it is capable of measuring all four Stokes parameters simultaneously. The third and fourth parameters are calculated by correlators which are based on commercial analog multipliers. The modification problem in general is also discussed. Calibration equipment is under construction and its function is briefly described
