摘要
短波宽带波形通过匹配近垂直入射天馈(NVIS)系统,可实现舰船、岸船通信的高速数据交互传输,极大提升短波通信在军事和应急通信系统中的作用.首先阐述国外典型的五种短波宽带波形的技术进展,然后分析宽带波形NVIS的可行性,利用ITU模型对不同数据速率和带宽对应信噪比下的链路评估,并进行了NVIS天波测试验证,为我国短波宽带波形在舰船、岸船使用NVIS宽带通信的实现提供评估方法和依据.
Abstract
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.
