Calibration of a Polarimetric Microwave Radiometer Using a Double Directional Coupler

Calibration of a Polarimetric Microwave Radiometer Using a Double Directional Coupler

This paper presents a built-in calibration procedure of a 10-to-20 GHz polarimeter aimed at measuring the I, Q, U Stokes parameters of cosmic microwave background (CMB) radiation. A full-band square waveguide double directional coupler, mounted in the antenna-feed system, is used to inject different...
