摘要:
When an h.f. radio circuit is being planned, the specification of the transmitter frequency range and radiated power and the choice of transmitting and receiving aerials are determined from propagation considerations. The factors involved in prediction techniques for the case of ionospheric signals are outlined. Current procedures used internationally and their proposed future improvements are described.
