摘要
为实现广播式自动相关监视(ADS-B)航迹与雷达航迹的高质量融合,必须对ADS-B航迹和雷达航迹数据质量进行分析。在分析实际ADS-B航迹数据的基础上,提出以航路为参考基准验证ADS-B航迹数据精度及完好性的方法。根据ADS-B报文中的位置导航不确定类别(NUCp)值,统计航迹点与航路中心线的水平偏差并将其作为位置实际误差,运用分位数-分位数图法对位置实际误差进行正态分布检验,得出置信水平为99%的实际误差置信区间,即在不同NUCp值下可信赖的位置误差范围。实验结果表明,在采用加权平均法进行航迹融合时,与传统权重分配相比,对于NUCp值为5或6的ADS-B航迹数据可增大权重,而对于NUCp值为7的数据则应减小权重。
In order to fuse the automatic dependent surveillance-broadcast （ADS-B） track with the radar track with high- quality, it is very important to verify the quality of ADS-B track data and radar track data, Based on the analysis of the actual ADS-B track data, a new method to validate the accuracy and integrity of ADS-B track data is proposed, which uses the route as the reference. According to ADS-B messages for different navigation uncertain category for position ;NUCp） values, the method uses the statistical bias between the track point and the route centerline as the actual location error. Using the Quantile-Quantile figure method to test the actual position error for normal distribution, the method gains the actual error confidence interval at the confidence level of 99%, which is a reliable error range for different NUCp values. When using the weighted average method to fuse ADS-B track and radar track, according to experimental results, we could increase the weight for the ADS-B track data of NUCp value being 5 or 6 and reduce the weight in the case of NUCp value being 7, which is different from traditional weight allocation.
