An Assessment of Wideband HF NVIS Curcuit Reliability
The high frequency(HF)wideband waveform through near vertical incidence skywave(NVIS)to realize the high-speed data communication of ship-ship or shore-ship communication,which will greatly improve HF military and emergency communication capability.First,this paper describes the abroad development of five typical wideband HF waveforms,then evalu-ates the curcuit reliability of NVIS signal-to-noise ratios(SNRs)corresponding different data rates and bandwidths by ITU model,finally analyzes the feasibility of the wideband HF through NVIS and carries out the NVIS skywave test for validation.This research provides an evaluation method of wideband HF waveform through NVIS communication on ship-ship or shore-ship.
