RESEARCH-ENGINEERING AND SUPPORT FOR TROPICAL COMMUNICATIONS.

Abstract

Communications research in a tropical environment is needed to develop improved equipment and techniques for use by military forces in Southeast Asia and other areas of similar environment. This report covers the following research effort in Thailand during 1 April through 30 September 1966: (1) Radio noise study and measurement. (2) Ionospheric electron content studies using Faraday rotation techniques on signals from beacon satellite S66; studies on ionospheric stability through Doppler technique applied to signal frequency dispersion, a study of disturbances in the earth's field using magnetometers. (3) Investigation of ionospheric factors related to local frequency prediction using oblique-incidence sounders. (4) Investigation of the effects of the tropical environment on antenna performance using airborne and man-carried antenna-pattern measuring systems (Xeledops); measurement of earth and vegetation electrical constants; theoretical model studies related to them.
