Abstract:

Methods for predicting the performance of high frequency ionospheric telecommunication systems are revised to include recent improvements in the basic ionospheric and geophysical data. Revised techniques for the processing of this data by high speed electronic computers is described in detail with emphasis on better statistical descriptions of the expected performance of radio systems depending upon ionospheric propagation of radio waves. The application of the prediction techniques to communication problems is illustrated and the concept of service probability in ionospheric telecommunication systems is introduced. Comparisons between predictions and circuit operations are shown.
