Analysis of DSCS (Defense Satellite Communications System) III SHF (Super High Frequency) Upgrades. Volume 1. Part A. Analysis of Frequency Reuse via Polarization Diversity.
Abstract
This report analyzes potential SHF upgrades to the DSCS III system. It is published in three volumes. This volume analyzes the effects of frequency reuse via polarization diversity on the DSCS system. This report describes the necessary improvements to both the space and ground segment needed to use dual-polarized signals in the DSCS system. The results of the study show that a 75- to 100-MHz cross-polarized channel would require major upgrades to both space and ground segments. A 15- to 25-MHz cross-polarized channel placed opposite a guardband would require only small improvements to the space and ground segments. Keywords include: DSCS III, Cross-Coupling Coefficient, Dual-Polarized Signals, Polarization Trackers, Axial Ratios, and Antennas.
