Abstract :
A dual-polarized radar was used in a year-long experiment to predict attenuation on two slant paths. The attenuation along these paths at 11.4 GHz was measured using a beacon transmission from an Intelsat V satellite. Drop size distributions for rain in the paths were calculated from the radar data and used to predict attenuation. Annual statistics were compiled from the measured attenuation data and from the radar predictions. Good agreement was found between the two sets of statistics. The paper describes the prediction techniques, and presents annual statistics for 11.4 GHz attenuation derived from the beacon measurements and from the radar predictions
