摘　　要：ADS-B作为新一代空中交通管制监视技术,其实时广播的飞行航迹报文,是监视空中交通运行情况的重要数据来源。在目标机动等情况下,传统算法对目标航迹跟踪性能降低,甚至可能丢失目标。提出基于改进当前统计模型的目标航迹滤波算法,该算法基于滤波过程中的残差信号及其协方差的变化,定义统计量并设定目标机动阈值,自适应调整模型过程噪声。仿真结果表明:该模型更贴近目标运动实际情况,改进算法的跟踪误差整体降低,尤其是在目标机动时,具有更稳定跟踪性能,跟踪精度更高。As a new surveillance technology in air traffic control system, ADS-B＇s real-time message of the flight target path is an important source of data for monitoring air traffic. When the target maneuver, the traditional tracking algorithm reduces the performance of target tracking or even loses the target. An improved current statistical model is proposed in this paper. The algorithm defines the statistic and the threshold using the changes of new information vector and its covariance to adaptively adjust process noise. Simulation results show that the tracking error of improved algorithm is lower, especially when the target maneuver, its tracking performance is more stable and the accuracy of tracking is higher.
