Abstract
Analysis of spatial correlation of rainfall rate and of slant path rain attenuation in order to optimize site separation and baseline orientation in site diversity design is presented. For this study, 4 years of rainfall rate measurements were obtained from the Hydrological Radar Experiment dense rain gauge network and associated radar facility in South England. The slant path rain attenuation correlations are analyzed for a hypothetical Earth-space propagation path at 20 GHz. Results show that the correlation of slant path rain attenuations at two diversity sites reaches a minimum at a separation of about 20 km between the two sites and a baseline orientation of acute angle above 30°.
