SIGNAL AMPLITUDE ANALYSIS OF HIGH-FREQUENCY CIRCUITS CROSSING THE AURORAL ZONE

Abstract

Pulsed trnsmissions at 12 and 18 mc from College, Alaska and Thule, Greenland were continuously monitored at Boston, Massachusetts for a period of nine months. Observed signal amplitudes are graphically presented and discussed for each of these months. Comparisons are drawn between the observed and predicted values of signal intensity and maximum usable frequency (MUF). The predicted values of signal intensity was 10 to 20 db higher than the observed signal intensity. The gross effects of the auroral zone on these circuits are discussed and anomalous behavior of the Thule-Boston 18-mc circuit near the MUF is presented. (Author)
