摘　　要：基于广播式自动相关监视(ADS-B)报文的位置导航不确定性指标(NUCP)的监视质量备受关注。针对位置导航不确定性参数好、监视质量却不高的问题,深入研究广播式自动相关监视报文数据项及其与基于性能的通信与监视的相关性。在充分考虑通信导航监视相关性及全球卫星导航系统(GNSS)广域增强等因素基础上,推导、构建了监视所需性能估计模型,并给予合理简化。在测试空域利用2个具有运行资质的生产商ADS-B接收站,连续采集近2亿条ADS-B报文,统计分析报文各信息项的状态参数,并应用到所需性能估计模型评估计算这两个ADS-B站的所需监视性能。此外还将参考文献报文参数代入模型评估所需性能。结果显示,当考虑报文各信息项统计状态及具备广域增强服务支撑时,ADS-B所需监视性能参数估计值未达到99.9%要求。若缺乏广域增强服务及相关性因素等,系统所需性能与国际民航组织(ICAO)监视要求的差距则更大。ADS-B technology is widely used in airspace surveillance.The surveillance quality of NUCPbased on its messages has attracted much attention.It has good NUCPparameters but poor surveillance quality.To address this problem,the correlation between the ADS-B data items and the performance-based communication and monitoring are analyzed.On the basis of fully considering the correlation between the communication,navigation,and surveillance,as well as the wide area augmentation of GNSS satellite navigation,the performance estimation model of the ADS-B surveillance system is deduced and constructed.And then a reasonable simplification had been carried out.In the experimental test airspace,two ADS-B receivers with operational qualification from different manufacturers are installed and operated.Almost 200 million ADS-B messages are collected in three months.The statistical distribution of each information item in the message is analyzed and calculated in detail.These results are applied to the estimation model to evaluate and calculate the required surveillance performance of the two ADS-B stations.And the parameters of message items in the references are applied in the model to evaluate the required performance.The results show that when considering the statistical distribution of each message item and the supporting of wide area augmentation,the surveillance performance of ADS-B systems do not meet the requirement of 99.9%.In the absence of wide area augmentation and the related factors,the required performance of the system is further from the ADS-B surveillance performance specifications required by ICAO.
