Abstract : This report presents current information on the observation, study, and analysis of various high frequency propagation measurements conducted over a path between the RADC experimental sites located at Stockbridge, NY, and the Panama Canal Zone. The discussions include an analysis of data collected on the two-hop E, two-hop ES, two-hop F, two-hop N, one-hopF, and the guided (FF) modes of propagation over the North-South, 3670 Km path. A determination of the loss and fading characteristics pertinent to each mode is presented. Granger oblique ionospheric sounders in addition to a high resolution 10 microsec pulse compression system are utilized to collect the ionospheric propagation data. Improvements in the instrumentation of the high resolution receiving system with emphasis on the recently achieved azimuthal angle of arrival capability are discussed. Preliminary azimuthal angle of arrival data are also presented in addition to analyzed data on short and long term, polarization fading effects. (Author)
