By analyzing the time-frequency distribution, Wigner-Ville distribution, and Wigner-Hough distribution of LFM (linear frequency modulation signal), and combining the relationship between FRFT (fractional Fourier transform) and the above time-frequency distribution, the possibility of using FRFT for fractional Fourier domain filtering is obtained, and the superiority of using FRFT for LFM signal filtering is verified through matlab simulation.
