Abstract : This report presents the results of sophisticated, high frequency, ionospheric propagation experiments that were conducted over a North-South path between the Panama Canal Zone and Stockbridge, NY. Granger oblique (forward) sounding systems and a spread spectrum, 10 microseconds width, pulse compression system were used to collect the data. Experiments were performed to separate and identify the various propagating modes, to determine the major constituents of losses and to identify their effects with each of the modes. The propagation modes on which data were collected and analyzed included the two-hop E, two-hop ES, two-hop F2, one-hop F2, N, M and several three-hop mixed modes. In addition to the measurement and analysis of long and short term absorption effects, polarization studies, azimuth angle of arrival measurements, and ionospheric disturbances investigations were conducted to determine their influence on the propagated modes.
