Abstract:

The requirements for a solar radio astronomy facility were investigated. Criteria were established for the various component parts of the radiometer receiver to be used in the solar radio astronomy facility. A first generator total power radiometer receiver was designed and con cstructed. Nuvistors were used in a neutrode arrangement in the RF amplifier and first IF amplifier. Drift curves were obtained showing a minimum detectable noise temperature of 5.5 K and a gain fluctuation of 0.5. A slowly varying component of the solar noise level was observed with a period of 15 to 20 minutes. Several Type 1 noise bursts were observed. The design of the second generation switched noise source comparison radiometer is also included. Author
