| Abstract: | The degradation of cross polarization discrimination (XPD)due to rain has been measured at 4 GHz using the Indian Ocean INTELSAT-IV satellite at Yamaguchi in Japan, where the satellite elevation angle is as low as 9 degrees. Based on the data obtained from August 1975 to October 1976, this paper describes the analyses on the cumulative time distribution of XPD,the correlation of XPD degradation with surface rain rate and rain attenuation, and the duration characteristics of XPD degradation. |
