Abstract:

Efforts were devoted to the design, construction and operation of a portable S-band radiometer capable of measuring noise temperatures from 2 to 500 K. The radiometer was constructed for the specific purpose of measuring the noise temperature of the 60-ft TD antenna. The results of these measurements will be used to determine the applicability of low noise receivers to the present tracking and data receiving system. The radiometer is useful for purposes other than antenna noise studies. Among these are antenna boresighting, measurement of loss in microwave components, and measurement of excess noise temperature of low noise receivers. The theory of operation of the radiometer is discussed along with the operating and calibrating procedures and descriptions and diagrams of the sub-units. A summary of results of tests on the 60-ft Vandenberg antenna is also included. Author
