Doppler shift and spread study for ionospherically propagated signals
Approved for public release; distribution is unlimited === Modern, High Frequency (HF) communication techniques, such as spread spectrum and frequency hopping, require precise signal frequency information. The predominant HF propagation path is via the ionosphere, which often produces Doppler freque...
