摘要
根据部分遥测缓变参数列表校准数据的处理需求,提出了应用光滑不等距插值算法进行回归处理的方法。阐述了光滑不等距插值方法的原理,介绍了该方法的软件处理流程,并应用试验数据对算法进行了验证分析。该方法具有光滑性好及精度高的特点,根据得到的各区间上惟一的插值多项式可求出任一点的精确值,克服了全局多项式和样条插值方法的不足。试验结果表明:该方法适用于校准数据呈非线性各类缓变参数的译解处理。
According to the processing need of calibration data for part telemetry slow-changing parameters,the regression processing method to use is puts forward in this paper.The principle of the smooth unequally-spaced interpolation algorithm is elaborated.The software processing flow of the algorithm is introduced.The verification analysis for this algorithm is performed with experimental data.It is proved that the algorithm has perfect smoothness and high accuracy.The precision value at any point can be derived by the unique interpolation polynomial of every subset.The shortages of spline interpolation method and the entire polynomial were overcome.The test result shows that the algorithm is suitable for processing any kinds of slow changing parameters when the calibration data is non-linear.
