摘 要:广播式自动相关监视(Automatic Dependent Surveillance-Broadcast,ADS-B)系统作为民航独立的监视手段具有一定的脆弱性。现提出基于卡尔曼滤波算法进行 ADS-B 航迹预测的方案,为进一步鉴别 ADS-B 位置信息的真伪提供可靠的技术支撑。通过解析 ADS-B 报文中的位置信息,建立卡尔曼滤波模型,计算航迹预测观测点数,完成基本的航迹预测实验。理论分析和仿真实验结果表明基于卡尔曼滤波算法的 ADS-B 航迹预测效果很好。

Abstract:Automatic Dependent Surveillance-Broadcast(ADS-B)system has a certain vulnerability as an independent surveillance means of civil aviation. In this paper,a scheme of ADS-B track prediction based on the Kalman filtering algorithm is proposed,which provides reliable technical support for further identifying the authenticity of ADS-B position information. Through analyzing the position information in the ADS-B message,the Kalman filtering model is established,the observation points of track prediction are calculated,and the basic track prediction experiments are completed. Theoretical analysis and simulation experiment results show that the ADS-B track prediction based on Kalman filtering algorithm has good effect.
