前言过去试飞测试系统经校准后,都要针对某一个参数得出一组校准数据,再将它们绘制成校准曲线。在处理光学记录器记录的试飞数据的时候,首先,用样板在记录纸带上量出参数对应光点的高度h,然后按着h 值大小在校准曲线上查出对应的物理量(图1)。用校准数据点绘制线曲,就是以人的视觉能力对具有测量误差的校准数据进行滑滤波,由于受视觉的限制,绘出的校准曲线不可能按着最佳形式通过数据点,除了增大了误差之外,译码速度也很慢,满足不了试飞测试精度和试飞进度的要求。为此,本文首先说明用回归分析方法来确定试飞测试系统的校准特性多项式,用它代替校准曲线;其次,说明把校准特性多项式存贮到计算器中,对光学记录器记录的试飞参数进行数据处理的方法。
Preface In the past, after the test flight test system was calibrated, a set of calibration data should be drawn for a certain parameter and then plotted as a calibration curve. When processing the test flight data recorded by the optical recorder, firstly, measure the height h of the parameter corresponding to the spot by using the template on the recording paper tape, and then find the corresponding physical quantity on the calibration curve according to the value of h (Figure 1) . Drawing a line with a calibration data point is a smoothing of the calibration data with measurement errors by human visual capabilities. Due to the limitations of the visualization, it is not possible to draw the calibration curve through the data points in the best form, except for increasing The error, the decoding speed is very slow, can not meet the test flight test accuracy and flight schedule requirements. To this end, this paper first describes the use of regression analysis to determine the calibration test polynomial test system, using it instead of the calibration curve; secondly, the calibration characteristic polynomial stored in the calculator, the optical recorder test flight parameters recorded data The method of treatment.
