In this paper time series spectra, both linear spectrum (FFT spectrum) and nonlinear spectrum (ar spectrum) are introduced briefly.
本文介绍了时间序列分析的线性谱(快速傅里叶变换fft谱)和非线性谱(自回归ar谱)。
The modal analysis and parametric identification are carried out. The ARMA mode and FFT spectrum analysis are used for these objects.
最后，用ARMA时序模型及FFT谱分析对此雷达进行了实验分析。
The second chapter recommends spectrum analysis with FFT.
第二章介绍了用FFT来进行谱分析；
