Comparison of antenna noise temperature with rain attenuation of a satellite beacon signal at 12 GHz
Abstract
Simultaneous measurements of antenna noise temperature and satellite beacon attenuation were made to examine the quantitative relation between them, and to determine the 'apparent' effective medium temperature which provides an accurate estimate of slant-path attenuation. The correlation between the attenuation and the increase in antenna noise temperature due to rain is very good, and the effective medium temperature derived from the 'apparent' one is reasonably consistent with a theoretical result.
