摘　　要：本文详细地讨论了匹配付里叶变换的离散形式 ,离散匹配付里叶变换与付里叶变换的区别 ;离散匹配付里叶变换频谱的周期性 ;采样对离散匹配付里叶变换的影响 .理论分析和计算机仿真表明 ,当采样频率低于线性调频信号带宽时 ,在一定范围内 。The discrete from of match Fourier transform is introduced in this paper.This paper discusses the difference of the discrete match Fourier transform and match Fourier transform and the effect of sample on the discrete match Fourier transform.The analysis and computer simulation demonstrate that if the sample frequency is lower than the LFM signal width,the signal may be separated.

关 键 词：采样 付里叶变换 线性调频
