11.7- and 20-GHz radiometric measurements at a Brazilian equatorial site
Abstract
The measurements were conducted with the aid of an Intelsat 3-meter receiving terminal to obtain statistical propagation attenuation data in an equatorial region. Manaus, Brazil, was selected as the site for the investigation because of the frequency of heavy rainfall on this location. The interpretation of the obtained data is discussed. Attention is given to the correlation of attenuation fades with heavy rainfall rates at the earth station, the correlation of attenuation fades with rainfall rates at a nearby meteorological station, and the correlation of attenuation fades at 11.7 and 20 GHz.
