| 摘 要： | 为提高空中交通管制系统的整体监视精度,在研究自动相关监视(automatic dependentsurveillance简称ADS)信息与雷达监视信息构成和特征差异的基础上,通过建立ADS目标与雷达目标之间的数据关联映射关系,构造了一个将ADS数据与多雷达数据融合处理的过程模型,提出了基于ADS报告周期调整ADS航迹与雷达航迹融合权重因子的可变周期更新算法。应用结果表明更新算法实现了两类信息的深度融合和对有效信息的综合利用,既保证了当ADS报告更新率较高时ATC监视的整体精度,又提高了ADS报告更新率较低时目标航迹的连续性,降低雷达测量误差对系统监视精度的影响,是一种用于空中交通管制系统监视数据处理的有效方法。

| Abstract: | In order to improve the surveillance performance of air traffic control system,the differences in contents and characters between ADS data and radar data were analyzed,the data mapping relation of multiradar target and ADS target was established,a new data fusion process model of multiradar data and ADS data was put forward,and a variable period updating algorithm was applied to determine the power factors of radar and ADS tracks in data fusion based on the position reporting period change of ADS information.Applied result shows that the algorithm can enhance information fusion depth and valid information utilization,ensure the whole accuracy of ATC surveillance when ADS data has a high updating rate,keep the smooth of target tracks when ADS report rate decreases,and decrease the influence of radar errors on surveillance system.It is an effective method for processing surveillance data in air traffic control system.2 tabs,4 figs,10 refs |
