摘　　要：机间数据链中使用定向天线技术能充分利用定向数据传输良好的隐蔽性、抗干扰性和抗截获性,但同时也带来一些难点问题。提出一种基于定向天线技术的机间数据链多址接入协议——动态优先级链式多址接入(DynamicPriority-Chain Link Multiple Access,DP-CLMA)协议。针对难点问题,给出协议相应的解决机制。最后分析了协议的时延和吞吐量性能,认为协议能够满足机间数据传输的作战需求。The application of airborne directional antenna in intra-flight data communication may result in some problems while improving the concealment capability,anti-interference and interception-resistance performance.A MAC protocol based on directional antenna,called DP-CLMA（Dynamic Priority-Chain Link Multiple Access） protocol was proposed in this paper.Some mechanisms were given for the DP-CLMA protocol to solve the problems.It is pointed out that DP-CLMA protocol may satisfy the requirement of intra-flight tactical data transmission based on analysis to time delay and throughput performance of DP-CLMA protocol.
