Abstract : The presence of the atmosphere acts to degrade the transmission of optical signals. Natural turbulence in the atmosphere induces amplitude fluctuations on a propagated optical signal. This report describes an experimental program conducted to determine the characteristics of amplitude scintillation. The study was aimed at defining the degree of scintillation incurred and the associated frequency spectrum for a source immersed in the atmosphere. Correlation studies were also undertaken to relate the scintillation characteristics to the meteorological parameters of the troposphere. The report briefly summarizes available knowledge of scintillation and then describes the program in detail. Information is given on the characteristics of the measurement system, flight test procedures, and meteorological instrumentation. Data reduction procedures and interpretation of results will be presented in Volume II. (Author)
