STUDY AND INVESTIGATION OF POLARIZATION PROGRAMMING. VOLUME II. POLARIZATION SYSTEMS ANALYSIS,
Abstract
The polarization programming problem is defined and a number of references in the study of polarization are given. The choice of frequency range based upon preservation of polarization is discussed and a few factors which can lead to depolarization at higher frequencies are mentioned. A somewhat detailed discussion is given of the polarization effects that take place in propagation via the ionosphere, with some emphasis on future applications to satellite communication. The troposcatter propagation factors affecting a polarization programming system are presented. A general mathematical description of polarized waves of all types and their transmission channel is given. The discussion includes antenna considerations. Two system philosophies and the field of applicability are discussed. Two appendices discuss a statistical model of a fading channel and a specific system incorporating one of the given design philosophies, respectively. The application of polarization programming to an over-the-horizon troposcatter link seems to be feasible, it should lie in the range of 1 to 10 kilomegacyles per second. (Author)
