The invention provides an extrapolation algorithm-based ADS-B (Automatic Dependent Surveillance-Broadcast) performance evaluation method, which comprises the following steps of: firstly, carrying out data preprocessing on collected ADS-B data and GPS (Global Positioning System) data, namely keeping the time of the ADS-B data and the GPS data consistent by using a data association algorithm; then deriving a reference horizontal position by adopting an extrapolation method, and establishing a delay model to evaluate the delay of the ADS-B data; and finally, evaluating indexes such as delay, horizontal position precision and horizontal position integrity of the ADS-B data by using the derived reference horizontal position. According to the method, the efficiency of ADS-B performance evaluation can be improved, the method is suitable for various scenes, the reliability is higher, and technical support can be provided for ensuring safe operation of ADS-B performance evaluation.

    本发明提供一种基于外推算法的ADS‑B性能评估方法,首先将收集到的ADS‑B数据和GPS数据进行数据预处理,即使用数据关联算法使二者时间保持一致;然后采用外推算法推导出参考水平位置,并且建立了延迟模型对ADS‑B数据的延迟性进行评估;最后利用推导出的参考水平位置对ADS‑B数据的延迟性、水平位置精度、水平位置完好性等指标进行评估。本发明方法可以提高ADS‑B性能评估的效率,并且适用于各种场景,可靠性更强,可以为保证ADS‑B性能评估的安全运行提供技术支持。
