Model Techniques for Interference Measurements.
Abstract
Results are presented of a study of the feasibility of applying model echniques to the analysis and measurement of antenna interference characteristics. Initial emphasis was directed toward modeling free-space, far-field phenomena, although some effort was applied to site modeling. The techniques described are capable of modeling antennas for measurements in and outside their design bands. The most advantageous characteristics of RF, hydroacoustic, and optical modeling techniques were combined to form a modeling procedure operable in 4 phases. Operational details of each phase are discussed, and data are presented to demonstrate the degree of correlation which can be obtained between full-scale and model measurements. Preliminary data lead to the conclusion that the modeling procedure provides an economical, flexible, simple, and reasonably accurate tool applicable to antenna and site interference analysis. A theoretical investigation into the radiation characteristics of horn-type antennas at nondesign frequencies was also conducted. (Author)
