样条插值方法在舰炮武器系统试验数据处理中的应用

摘要

针对舰炮武器系统试验数据处理中,线性插值法在数据拐点处或导数变化率较大时数据拟合失真的问题,提出了应用样条插值方法进行数据拟合插值的观点.给出了三次样条插值的最佳转换公式,并以工程实践中舰炮武器系统试验航路为实例,应用样条插值方法拟合处理试验数据,其精度满足试验要求.%Aim to all kinds of problem about test data processing of naval gun system, such as date approach distortion in date turning or derivative inflection major with linear interpolation. The auther cames up with a proposition of applying spline interpolation in the data processing. Cube spline interpolation is formulated, and an example of naval gun system test routes is made. To apply spline interpolation to deal with test data, the precision completely meets the need of tests.
