摘　　要：机载超短波通信系统主要承担飞机对外语音信息、情报信息及态势信息等多种信息的传输工作。在日常使用中,机载超短波系统需要基于不同的任务需求配置功能线程,以完成多路机载话音、数据链传输任务。传统的静态调度方法越来越难以满足日益增长的通信需求,同时也造成链路资源开销大、冗余高的问题。基于以上问题,提出了一种基于天线分时复用的动态链路调度策略及具体实现方法,包括天线资源管理、功能线程状态监测和资源仲裁策略等;针对动态调度天线可能造成接收信号不连续的问题进行了影响分析,结果表明合理配置天线切换周期能够保证正常通信。The airborne ultra-short wave communication system is mainly responsible for the transmission of various information such as voice information,intelligence information,and situation information.In daily use,airborne ultrashort wave systems need to configure functional threads based on different mission requirements to complete the tasks of multi-channel airborne voice and data link transmission.Traditional static scheduling methods are becoming more and more difficult to meet the growing demand for communication,and at the same time,they also cause problems such as high link resource overhead and high redundancy.To solve above problems,a dynamic link scheduling strategy based on antenna time-sharing multiplexing and its specific implementation method are proposed,including antenna resource management,functional thread status monitoring and resource arbitration strategy.The impact analysis of the problem that the dynamic scheduling antenna may cause the received signal to be discontinuous is analyzed.Results show that the rational configuration of the antenna switching cycle can ensure normal communication of the function.
