滑动容错辨识算法在航迹数据处理中的应用

由于试验环境和被测目标运动特性的影响,航迹测量数据中会出现斑点型异值。对最小二乘多项式进行改进,引进自适应调节函数和滑动窗口概念,提出了滑动多项式容错辨识算法,详细描述了采用该方法进行异值辨识和修复的具体过程。仿真分析和实际飞行试验的数据处理表明:该方法对处理含有斑点型异值的测量数据具有良好的效果。

Application of Fault-tolerant Sliding Algorithm in Trajectory Data Processing

Trajectory data may contain outliers with the influence of test environment and motion properties of the tracked objects.So a new method is presented to improve least square,and the function of self adjustment and concept of sliding windows are introduced.Then a fault-tolerant sliding algorithm,and the main procedure of identification and remove of outliers are provided which is discussed detailedly and applied to a series of outliers identification.Simulation analysis and data processing of actual flight test indicate that this method is a good way for processing of measurement data with a series of outliers.
