基于ADS-B的实时航迹精度评估模块设计

Design of ADS-B Based Real-time Accuracy Evaluation Modular of Track Measurement

面向对空情报雷达可在日常工作状态中掌握和评估自身探测性能的需求,设计实现了一种实时航迹精度评估算法。以民航目标的ADS-B数据为参考基准,将雷达测量航迹与其进行时空对准,实时计算对目标航迹的测量精度,同时对结果进行可视化输出。经装备实际验证,该模块具有全天候、高可靠性的特点,可连续更新系统的探测精度,为雷达标校提供参考依据。

In daily work conditions, air surveillance radar often needs to assess its detection performance. According to this requirement, a real time track accuracy assessment and visual analysis module is designed and implemented. The algorithm module uses ADS-B data as datum reference, after space-time alignment with the track detected by radar, the measuring accuracy can be calculated in real time, and finally analysis results are provided. The actual operation shows that this module has the characteristics of all-weather and high reliability;it can update the track accuracy continuously and provide reference for radar calibration.
