Research On Key Technologies Of Fast Hopping Frequency Tactical Radio

The digitized army is the inevitable trend of modern military, the digitization of communication means is the most important condition of realizing the digitized army. An important problem in modern military communication is the anti-jamming and how to prevent and reduce the mutual jamming in communication networks has become a difficult problem. The FH (Frequency Hopping) Communication is a branch of Spread Frequency and its prominent merit is anti-jamming. Thus, it's much suitable for the military domain. Because of its remarkable resistance ability to jamming, the tactical High-Speed FH radio has become the research hot spot of every country's army. This thesis researches on the key technologies of the tactical High-Speed FH radio.On the basis of reviewing the FH Communication, the thesis elaborates the significance of tactical High-Speed FH Radio, analyzes the key technologies of tactical High-Speed FH Radio, and then proposes a scheme of tactical High-Speed FH System. It researches on the key technologies of FH Communication with emphasis, including: design and realization of FH sequence based on clock and secret key; design and performance analysis of frequency-hopping synchronization control plan in Ad hoc network; the research on auto-adapted FH technology. Then designs and analyzes of a auto-adapted channel quality estimate algorithm based on the SNR. Finally, summarizes the key technologies of tactical High-Speed FH Radio and forecasts the following works.
