Extraterrestrial radio noise and its effect on radar performance
Abstract
In this paper, the flux densities of radio frequency radiation from the quiet Sun and other cosmic noise sources are presented as a function of frequency. The conversion of flux density to apparent antenna temperature is discussed. An evaluation is made of UHF radar system degradation, i.e., the reduction of radar-range capability, due to the presence of the Sun, discrete radio stars and distributed noise sources in the Galaxy.
