基于ASTERIX标准的终端数据交换

Terminal Data Exchange Based on ASTERIX Standard

文章首先介绍了采用通用化、标准化、结构化、可扩展化的ASTERIX标准的必要性及背景信息;然后阐述了UAP帧结构的具体组成和内容;最后参考2019.3.4号发布的最新版本CAT048协议,制定了航迹UAP,并且详细地分析了数据帧的解析过程。通过使用实体雷达航迹UAP、点迹UAP等的必选和选配功能,不仅可以提高软件产品的灵活性、可修改性、可扩展能力,更能在实际应用中不断丰富实体雷达的终端特色数据项及具体内容。

Firstly,the necessity and background information of the all-purpose,standardized,structured and extensible ASTERIX standard is introduced briefly;then the composition and content of the UAP frame structure is described in detail;and finally,the track UAP is established and the analysis process of data frame is analyzed in detail after using the latest version of the CAT048 specification issued on March 4,2019 for reference.By using the necessary selection and optional selection function of the actual radar's track UAP and plot UAP,not only the flexibility,modifiability and expandability of the software product can be improved,but also the characteristic data items and contents of the radar terminal can be enriched continuously in the practical application.
