摘要
目前的V/UHF地空战术数据链主要以固定时隙分配模式工作,存在着用户容量与信息刷新速率之间的矛盾。针对这一问题,结合新一代地空战术数据链的需求,通过分析空中态势信息和指挥引导信息的传输和要求,提出了一种基于FDM-TDM的V/UHF地空战术数据链传输方案,该方案在保证较高信息刷新速率情况下,可使指挥引导飞机容量增加5倍以上。
The work pattern of V / UHF air ground tactical data link mostly is of fixed time apportion. So there exists a contradiction between user capacity and information update velocity. Increasing user capacity could make the information update velocity slow, and expediting information update velocity could cause the user capacity to decline. Aiming at this problem, and considering the demand of new generation air ground tactical data link, after analyzing the transmit requests of air - state information and direct -induct information, a kind of V / UHF air ground tactical data transmit scheme based on FDM - TDM is proposed. The analysis and experiments prove that by adopting this scheme the user capacity will increase 5 times more, and simultaneously the information update velocity is still kept speedy.
