Abstract

The wave propagation experiments using Japanese geostationary satellite Superbird-C have been performed at the Universiti Sains Malaysia earth station. A relationship between rain depolarization and attenuation, valid for earth-space path at microwave wavelengths, is presented. Cumulative rain attenuation and cross-polarization discrimination (XPD) statistics are given for the period of 4 years (2002-2005) at 12.255GHz. XPD varied from 44 dB at 1% to 16 dB at 0.001% of time the abscissa is exceeded. Comparisons were made with available data sets and with five simple XPD models and the results indicate a good performance by the simple isolation model and the CHU model compared with the others. These results serve as checks on the theoretical models needed for predicting communication system performance in geographical regions especially for equatorial climate where measurements are not available.
