基于一维快速傅里叶变换FFT频谱估计的移动物体速度估计法-Estimation of moving objects based on one-dimensional fast Fourier transform FFT spectrum estimation speed

用DFT（FFT）对信号进行频谱分析，离散傅里叶变换（DFT）对有限长时域离散信号的频谱进行等间隔采样，频域函数被离 散化了，便于信号的计算机处理。 -Using DFT (FFT) spectral analysis of the signal

基于matlab的傅里叶频谱分析实验报告，可作为信号系统和通信原理的实验参考。-Based on matlab Fourier spectrum analysis experimental report, can be used as a signal system and communication principle of experimental reference
