Concept-Level Analytical Procedures for Loading Nonprocessing Communication Satellites with Direct-Sequence, Spread-Spectrum Signals.
Abstract
This report is the second in a series devoted to presenting the analytical procedures and mathematical formulations required to construct a computer model of a military communication satellite system, load it efficiently with the radio signals required to support an operational scenario, and assess its vulnerability to jamming. It does not address the implementation of the model. Like MR-639-AF/A, the first report of this series, the analysis is restricted to nonprocessing, frequency-translating (or 'bent-pipe') transponders. However, instead of being operated in the linear mode, as was necessary there to accommodate the frequency-division-multiplexed, nonantijam signals being considered, the transponders here are considered to be driven deliberately into saturation and to behave like hard limiters. This is done to obtain the best possible performance (in a jamming environment) of the direct-sequence, spread-spectrum signals of interest. Such so-called anti-jam signaling is important to military communications because of the significant protection it can provide against jamming.
