| 摘 要： | 在飞行器试验数据处理中,人们通常用最小二乘方法采用一条多项式曲线来拟合测量数据,为了提高曲线拟合的精度,本文提出采用样条函数来拟合测量数据,另外,对观测噪声未知的情况下,讨论了自适应样条滤波。本文讨论的方法采用了线性模型。

| Abstract: | When processing the test data of a vehicle, a polynomial curve is often applied to fit the measured data by least square method. The paper provides a spline function to fit the measured data for enhancing accuracy of the fitting curve and studies an adaptive spline filters' method for unknown measured noise. The method dissussed in the paper adopts a linear model. |
