摘　　要：针对短波通信系统设备种类多、数量多、操作复杂、升级成本高、兼容性差的问题及现代信息战的发展需求,论文提出了一种基于软件无线电的短波通信系统软硬件平台设计方案,硬件平台采用总线式组织结构和分频段、二次变频的射频收发模块,实现了模块级的可扩展化和中频与基带处理模块的通用化。软件平台则使用与SCA规范(Software Communication Architecture)完全兼容的OE波形实时运行环境和波形开发部署管理工具。该系统支持新业务功能的软件注入和硬件资源的无缝扩展,较好地解决了短波通信系统中所面临的相同设备功能扩展升级和不同设备互连互通的问题。Considering the growing demand of communication and navigation integration, and many disadvantage of nowadays HF com- munication system such as massive device type, the complexity of operation, high cost to upgrade, poor compatibility, etc, this article pro posed a design scheme of HF system based on Software Defined Radio. The hardware platform realizes the module^level scalable and universal of the IF and baseband processing module, by adopting the bus-structure and the novel designed RF transceiver module with divided band and double-time frequency-conversion. The software platform introduces the real-time operation environment and the waveform development, de- ployment and management tools compatible with the SCA criterion. The HF system supports the injection of new functions and seamless ex- tension of hardware resources, thus solves the problems in the extension or upgrade of the transceiver and intercommunicate of diverse trans ceivers.
