FREQUENCY ASSIGNMENT STUDIES.
Abstract
This is a study to improve electromagnetic compatibility in the field army through development of frequency assignment practices. Theoretical problems inherent in efficiently apply mutually interference-free frequency groups to radio networks are analyzed. The problems are formulated in a mathematical structure and methods of solution are presented. Both are shown to be analogous to those encountered in replication of radio -frequency assignment. A simple graphical aid is developed to determine far-site exclusions bounding frequency assignment. The aid is applied directly to the map overlay of a network and greatly facilitates determination of the exclusion data required. Assignment grid-overlay methods are analyzed and problems isolated. Design procedures for grid-overlay methods are formulated and used to develop representative systems. A tentative comparison of the efficiency of grid-overlay systems and more direct application of class-theory expressions is considered. Radio-net operation is analyzed with both on-site and far-site problems considered. The basic complexity of exact analysis is demonstrated, and the need for a synthesis approach shown. (Author)
