A 94 GHz differential radiometer for observations of diffuse sky emission
The design and performance of a portable 94 GHz differential radiometer is discussed. The antenna system is an off-axis paraboloid-hyperboloid combination with a field of view of about 50 arcmin. All mirrors are made of carbon fiber coated with silver. Beam switching is obtained by wobbling sinusoid...

The design and performance of a portable 94 GHz differential radiometer is discussed. The antenna system is an off-axis paraboloid-hyperboloid combination with a field of view of about 50 arcmin.

This radiometer was used in Antarctica (Italian Base, Terra Nova Bay, -74 S, +164 E) to make measurements to the diffuse sky emission at mm wavelengths.
