AIR-GROUND METEORIC SCATTER COMMUNICATIONS

Abstract

Results are presented of a study and program to develop air-ground long-distance communications by reflecting radio-frequency signals from the ionized trails generated by meteors entering the earth's atmosphere. In point-to-point tests, the breadboard model transmitted messages over a distance of about 1460 km. Test results obtained during the most unfavorable part of the day indicated half-hourly data rates of eight words per minute. Waiting times of less than four minutes were observed for 95 percent of the time. The modulation technique employed was frequency shift keying. The capability to utilize frequency shift keying or phase shift keying was planned for the air-ground test. The meteoric scatter system developed may be useful as a back-up for present primary communications in transferring high- priority information at a low rate. (Author)
