Abstract

Results are presented of experimental measurements of the angle of arrival and amplitude of the individual rays in a multipath microwave propagation situation. On the basis of extensive data collected on a 31.5-km path, statistical distributions that are expected to be of assistance in the design of diversity, especially angle-diversity, microwave systems are presented. In the application of the technique, a sampling interval of 1 s appears to be sufficient to capture the variations in the individual paths, and the range in angle of arrival (1.4°), determined by the element spacing, appears to be sufficiently wide to avoid aliasing problems
