Abstract:

This report describes the methods used and the affirmative results in validating a computer program developed for the Army to determine the effect of high level radio frequency radiation on missile systems. The methods described were used to uniformly radiate models of transmission lines by high level radio frequency radiators at White Sands Missile Range, New Mexico, and by coupling at a single location in the Test and Reliability Evaluation Laboratory, Research and Development Directorate, U. S. Army Missile Command, Redstone Arsenal, Alabama. New methods of computing and measuring the effects of effective resistance and permeability of conductors and the dielectric constant and dissipation of insulation are discussed. Effects of sunlight on dielectrics were measured. Measurements verified the computed characteristics of coupling of radio frequency power injected into the model at discrete locations to simulate nonuniform shielding and the effects of mismatched terminations with reference to the complex characteristic impedance of the models. New techniques are given for determining the absolute field strength present at the exact location of the model immersed in an electromagnetic field. Author
