Around-the-world propagation of short radio waves

In the present book, a theory of around-the-world high-frequency propagation is outlined in a systematic fashion. Particular attention is given to the influence of ionosphere-ionosphere reflections on long-distance and around-the-world high-frequency propagation and to methods of calculating global propagation paths. Some aspects of the investigation of high-frequency echoes and of calculating ionospheric propagation conditions for antipodal high-frequency radio signals are discussed.
