TROPICAL PROPAGATION RESEARCH
Abstract
The over-all purpose of this program is to provide basic information about radio propagation phenomena that can be used to improve communications equipment and techniques for military forces in Southeast Asia and other areas with similar environments. The first comprehensive series of measurements of propagation and environmental data has been obtained in a wet-dry tropically vegetated area in Thailand in the vicinity of the town of Pak Chong. Propagation measurements have been made at discrete test frequencies in the 100-kc to 10-gc range. A major portion of this program is concerned with the collection and analysis of basic data on radio propagation in relation to the physical characteristics of the natural environment that influence propagation losses. These characteristics include terrain features, climate, vegetation, and radio noise. The quantitative effects of the environment upon radio propagation losses are being studied through correlation analysis. The information thus obtained will be used to develop a comprehensive model that will permit practical predictions of range performance of tactical mobile communications equipment in an tropical encironment. The field measurements originally planned in the 100-kc to 425-mc frequency range at Pak Chong were essentially completed during this reporting period. This report summarizes the results of these measurements and presents certain tentative conclusions which can be drawn from the work thus far.
