Abstract
As described in previous articles, a unique experimental method was used to test the new Beam Waveguide (BWG) antenna at Deep Space Station 13 in the Goldstone Deep Space Communications Complex near Barstow, California. The methodology involved the use of portable test packages to make measurements of operating noise temperatures and antenna efficiencies (as functions of antenna pointing angles) at the Cassegrain focal point and the final focal point located in a subterranean pedestal room. Degradations caused by the BWG mirror systems were determined by making comparisons of the measured parameters at the two focal points of the antenna. Previous articles were concerned with the design, performance characteristics, and test results obtained with an X-band test package operating at 8.45 Giz. This article discusses a Ka-band test package designed for operation at 32 GHz. Noise temperature measurement results are presented for the Ka-band test package in an “on-the-ground” test configuration.
