为有效提高飞机的监视精度,获取准确的飞行航迹,针对ADS-B监视过程中的航迹异常问题,提出了基于基本飞行模型的ADS-B航迹修正方法。该方法充分利用ADS-B丰富的飞行数据信息,建立了飞行计算模型和航迹识别模型,最终结合真实数据通过程序仿真验证了该方法的可行性。实验结果表明,该方法能准确、快速修正平飞、转弯、爬升过程中的航迹信息,可以有效提高航迹监视的实时性。

In order to improve the accuracy of the aircraft monitoring, and to obtain the accurate flight track, ADS-B track correction approach based on basic fight model is put forward to solve the problem of abnormal track in ADS-B monitoring process. The algorithm makes full use of ADS-B flight data information and establishes the flight calculation model and trajectory identification model. Finally the feasibility of the algorithm is validated by using real data. The result shows that this method can accurately and fast correct the track information in level flight, turning and climbing process; meanwhile, it can effectively improve the accuracy of the flight track monitoring.
