Abstract:As the LFM signal can produce a good concentration in the CDFRFT (Centered discrete fractional Fourier transform) domain, a novel method for LFM ( Linear Frequency Modulation, LFM) signal Parameter estimation based on CDFRFT is proposed after the introduction of the Centered discrete fractional Fourier transform in this paper. The result of the experiments shows that the algorithm is efficient in estimating the parameter of both single LFM signal and double LFM signals.
Keywords:Centered discrete fractional Fourier transform LFM signal Parameter estimation
