Abstract : This is the final quarterly technical report on a one-year contract to extend and improve an existing empirical model for worldwide behavior of ionospherically imposed radio-wave scintillation. The objectives of the project were (1) to improve the accuracy of model-based calculations of the intensity- scintillation index and (2) to develop a capability for full description (from the point of view of engineering applications) of the first-order, complex- signal statistics that characterize the trans-ionospheric radio communication channel. A follow-on project has been initiated to extend the channel model to include second-order signal statistics in the temporal, spatial, and spectral domains. The first priority in the follow-on work will be to calculate the fluctuation spectra of relevant signal parameters. In addition, it is intended to extend validity of the model into the multiple-scatter regime.
