| Abstract: | 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. |
