Abstract:

Nuclear event induced atmospheric scintillation can have an adverse effect on communication systems of all types. Satellite communication systems are particularly susceptible to channel disruption resulting from atmospheric scintillation. This report documents the preliminary results of an effort to develop a tool to assist communication system designers. Various simulation and models attempt to characterize the dynamics of a nuclear perturbed atmosphere. The report focuses on resolving apparent differences of primary interest to the context of Radio Frequency phase relationships are addressed relative to a number of commonly used transmission schemes.
