飞参通道标校插值误差分析及标校点设置

Error Analysis of Calibration Interpolation and Setting of Calibration Points in Flight Data Channel

飞参通道标校点的合理选取是保证飞参数据解码准确性的关键。针对飞参数据采用插值标校过程中标校点不容易选取的问题,分析如何合理选取标校点。通过对插值标校法误差和插值点区间误差极值存在性的分析,提出了选择标校点的几点要求。根据要求,设置了8个标校点,提高了解码精度和的运行效率。

The reasonable selection of calibration points of flight data channel is the key to ensure the decoding accuracy of flight data.In view of the problem that it is not easy to select the successful calibration point in the process of interpolation calibration of flight data,this paper analyzes how to select the calibration point reasonably.Based on the analysis of error from the interpolation calibration and the existence of extremum of interval error of interpolation point,this paper puts forward several requirements for selecting calibration point,and sets eight calibration points according to the requirements,which improves the decoding accuracy and operation efficiency.
