| 摘 要： | 为了获取更多有效信息,将谱分析方法应用于惯性平台试验数据的定性分析。首先对试验数据进行差分处理得到平稳数据,再利用快速傅里叶变换就能得到数据的频谱。对某次试验数据进行处理后得到的频谱图进行了分析,结果表明此方法简单、有效。

| Abstract: | For the sake of getting more effective information,frequency spectrum analysis is applied to qualitatively analyze experimental data of inertia platform.Firstly,disposing experimental data by difference method and getting smooth data.Then using the discrete Fourier transform method to dispose the smooth data and getting frequency spectrum figures(FSF).FSF of an experimental data are analyzed,the result indicates the method is simple and effective. |
