PREDICTING THE PERFORMANCE OF BAND 7 COMMUNICATION SYSTEMS USING ELECTRONIC COMPUTERS

Radio system parameters are combined with geophysical and ionospheric characteristics to predict the performance of high frequency sky-wave communication circuits through the use of electronic computers. A program is presented to compute maximum usable frequencies, optimum traffic frequencies, lowes...

Zusammenfassung:	Radio system parameters are combined with geophysical and ionospheric characteristics to predict the performance of high frequency sky-wave communication circuits through the use of electronic computers. A program is presented to compute maximum usable frequencies, optimum traffic frequencies, lowest useful frequencies, probable mode of propagation, angle of arrival, circuit reliability, system loss, available signal-to-noise and field strength. Numerical representation is used for all parameters not expressed in closed mathematical form.
