Radiometric sensitivity measurements have been made on a quasi-optical receiver in the spectral range 170 mu m to 1 mm. Using GaAs Schottky mixer diodes in a corner reflector configuration, a total system noise temperature of 9,700 K (DSB) has been o

We have made heterodyne radiometric measurements with GaAs Schottky diode mixers, mounted in a corner‐reflector configuration, over the spectral range 170 μm to 1 mm. At 400 μm, system noise temperatures of 9700 K DSB (NEP=1.4×10−19 W/Hz) and

A 28-foot diameter antenna, operating at wave lengths of 8.5 mm, was installed and tested. This report describes the evaluation of the test range and the electrical testing of the antenna at a wavelength of 8.5 mm. A series of grain, pattern, and bor
