Comparative Analysis of Passive Communications Satellites Employing the SHF and HF Spectrum for Use in a Strategic Role

Abstract

Passive communications satellites were instrumental in the evolution of todays satellite communications networks. However, ever since the successful deployment of the first geostationary satellite, research and development into passive communications satellites has almost come to a halt. In addition to examining the characteristics of the historic passive satellites, this thesis will evaluate the capabilities of a new design approach for a passive system. The passive backscatter array, which was initially proposed by Joseph Yater, was intended to provide an effective communications satellite with a large radar cross section. Primary emphasis is placed upon this system's survivability within a nuclear stressed environment. The effects of a nuclear burst upon the propagation of an electromagnetic signal are evaluated so as to assess systems survivability. Keywords: Passive satellite communications, PACSAT, Echo satellites, Nuclear blast effects, Ionosphere degridation, Strategic communications, Theses.
