Abstract
The report presents the results of a microwave propagation experiment which was conducted in the 11 GHz and 17GHz frequency ranges on two adjacent 16 km paths near Ottawa, Canada. Direct and cross-polarized signal levels were measured for six months in mid-1979, and significant attenuation and depolarization were observed during periods of rainfall as well as at certain times when the atmosphere was clear. The probabilities of occurrence of attenuation and depolarization, and the relations between them, comprise a major part of the report. Statistics of the durations and of the rates-of-change of attenuation are also presented. There is also a discussion of the relation of depolarization during rainfall to the canting angles of raindrops, and a procedure is developed by which the statistics of the canting angles are obtained.
