民航自动化系统多监视源融合时丢失一次信号原理浅析
Analysis of the Principle of Losing Primary Signal in the Integration of Multiple Surveillance Sources in Civil Aviation Automation System

空管自动化系统是整个航空部门对空指挥的核心系统，能够实现对雷达监视数据的处理，为管制员提供飞行态势状况报告，对异常情况进行预警。飞行数据的处理，能够实现雷达航迹与飞行计划相关。本文针对多监视源融合过程中丢失一次雷达信号的情况分析了系统日志，深入梳理了监视源信号的处理逻辑和融合机制。通过研究结果，深入了解了二所自动化当前版本的多监视源融合机制，为日后的多监视源融合方面的故障排查提供有力支撑。
The air traffic management automation system is the core system of the entire aviation department’s air command, capable of processing radar surveillance data, providing controllers with flight situation status reports, and issuing early warnings for abnormal situations. The processing of flight data can correlate radar tracks with flight plans. This article analyzes the system logs for the situation where a radar signal is lost during the integration of multiple surveillance sources, thoroughly combs through the logic of surveillance source signal processing and the integration mechanism. Through the research results, an in-depth understanding of the current version of the multi-surveillance source integration mechanism of the Second Institute’s automation has been gained, providing strong support for troubleshooting in the area of multi-surveillance source integration in the future.
