Savitzky-Golay滤波方法在末敏弹稳态扫描测量数据处理中的应用研究

摘要

末敏弹稳态扫描数据测量精确与否直接关系到末敏弹在实战中能否锁定目标并形成精确打击,而在以往的稳态扫描数据处理中,应对波形记录数据出现削波、抖动及小信号现象处理不准确,作者提出应用卷积方法对数据进行最小二乘平滑和微分处理,建立完整的数据测量及后续处理的程序模型.实验结果表明:该方法扫描角数据处理较峰峰法测量精度更高,能够很好地克服转速测试常见波形问题,测试结果精确,可以应用于末敏弹稳态扫描数据处理程序中.%The accuracy of the data measurement the terminal-sensitive missile is directly related to whether the target can be locked in the actual combat and form a precise blow.But in the past steady state scanning data processing,the problem of inaccurate processing of clipping,jitter and small signal phenomena in waveform recording data is proposed.In this paper,the least squares smoothing and differential processing of data are proposed by using convolution method,and a complete data measurement and subsequent processing of the program model,the application of the above method was used to calculate the scanning angle and speed.The experimental results show that the method is more accurate than the peak-to-peak method in scanning angle data processing,and the speed test can overcome the common waveform problem very well,and it is more accurate than the peak test method.And it can be used in the elastic steady state scanning data processing program.
