Abstract
The EUT radiometer system has one antenna of a beam waveguide type consisting of a multifrequency scalar horn and four reflectors. The 20/30 GHz radiometers operate according to the Dicke principle, the 12 GHz radiometer follows the total power principle. The temperature of the electronic circuits has been kept constant at a temperature of 310 ± 0.01 K.
