The invention discloses a multi-source ADS-B (Automatic Dependent Surveillance-Broadcast) data anti-jump rapid fusion method and system. The method comprises the following steps: receiving an ADS-B message and acquiring multi-source ADS-B track data of a target flight; according to the ADS-B track data, obtaining a first target track set according to 24-bit address codes; according to the ADS-B track data, using distance, height and course difference to determine whether the first target track set satisfies a secondary segmentation condition, and according to a determination result, obtaining a second target track set; according to the ADS-B track data use distance, the flight number and the secondary code, judging whether a second target track set meets a triple segmentation condition, and according to a judgment result, obtaining a third target track set; and judging the number of elements in the target track set which cannot be segmented again based on the three segmentation results, and obtaining a fusion track. According to the method, the accuracy of ADS-B track data output by the system is improved, and support for decision making of a controller is enhanced.
本发明公开了一种多源ADS‑B数据防跳变快速融合方法及系统,方法包括:接收ADS‑B报文并获取目标航班多源ADS‑B航迹数据;根据所述ADS‑B航迹数据按照24位地址码得到第一目标航迹集合;根据所述ADS‑B航迹数据使用距离、高度以及航向差判断第一目标航迹集合是否满足二次分割条件,并根据判断结果得到第二目标航迹集合;根据所述ADS‑B航迹数据使用距离、航班号以及二次代码判断第二目标航迹集合是否满足三次分割条件,并根据判断结果得到第三目标航迹集合;基于三次分割结果判断不可再被分割的目标航迹集合中元素个数并获取融合航迹。本发明提高系统输出ADS‑B航迹数据准确性,增强对管制员决策的支持。
