Data Fusion of ADS-SSR in Air Traffic Management
-
摘要: 二次监视雷达(SSR)和自动相关监视(ADS)系统已经广泛应用于空中交通管理(ATM)系统,特别是终端飞行区.本文分析了民航空中交通管理中的SSR和ADS系统的特点和缺陷,研究了基本类型ADS合同和扩展类型ADS合同对ADS跟踪精度的不同影响,提出了一个ADS-SSR航迹融合的模型,给出此模型的具体算法,并进行了数字仿真.数字仿真表明:该模型算法具有较高的跟踪精度.Abstract: The application of Secondary Surveillance Radar (SSR) and Automatic Dependent Surveillance (ADS) have been applied in Air Traffic Management (ATM) system widely, especially in terminal domain. The characteristic and limitation of SSR and ADS in civil aviation are analyzed. The different affections of basic ADS contracts and extended ADS contracts to tracking precision are also deeply studied. A model and algorithm of the data fusion of ADS-SSRin civil aviation are presented for improving the tracking precision. The numerical simulation shows that this model and algorithm are effective. It is helpful for ATM system to have a continuous and reliable surveillance in a whole flight.
