Instantaneous frequency scaling of rain attenuation at 11.6-17.8 GHz with SIRIO data
Abstract
The present study provides results pertaining to the instantaneous frequency scaling of rain attenuation (CPA) as obtained from measurements carried out with the Italian SIRIO satellite. The frequencies employed are 11.6 GHz (downlink) and 17.0-17.8 GHz (uplink) in circular polarization. The experiment made it possible to measure jointly the attenuation at two widely spaced frequencies for a long period of time (three years). The work presented is based exclusively on excess attenuation due to rain. Attention is given to the SIRIO satellite main characteristics, the LARIO earth terminal main characteristics, and the ratios between the attenuation at the same probability level.
