AN EXPERIMENTAL AIRBORNE 50 MCPS IONOSPHERIC SCATTER COMMUNICATION CIRCUIT

Abstract

A two-way VHF air-ground-air ionospheric scatter communications experiment is described. The data, consisting of field strength measurements and baud error counts, indicate that an airborne teletype system using this mode of propagation is feasible to distances of approximately 1200 statute miles with known techniques and available equipment. Information is presented concerning the variation of the baud error rate with the number of diversity branches. The system performance during operation across the auroral zone at times of magnetic disturbances is discussed. Recommendations are made from which an operational system could be developed. (Author)
