Research On VHF Communication In C~3I System's Application

The C3I system called military strength intensifier can provide the important surroundings which advances the auto-command power,quick response ability and systemic combat capability for the communication electronic war. So, building a C3I system with good automatization and excellent anti-interference has the important meaning for army modernization. Generally, the VHF communication is the primary radio-communication instrument of the tactics C3I system.The design of the VHF communication net affects the most important performace, such as the quality,distance,capacity of communication net and the flexibility of system.Therefore, the research of the VHF communication technology adapt to the tactics C3I system has the practical meaning.This thesis introduces the correlative principle of the VHF communication and it's characteristics has been analysised. Then the project problems, such as installltion of attenna,design of the link,electromagnetic compatibility have been discussed under the demand of a factual system. The difference about capacity and efficiency of different communication-nets is the emphases of this paragraph. And an design which is adapt to the system is given.Simultaneity, an equipment of the expand application of VHF station has been gived to enhance the quality and capacity of the radio communication net of system.Finally, the correlation data of account and experimentation is given to prove the feasibility and rationality of the design.
