摘要
The aim of this paper is to propose a novel technique for the detection of multicomponent chirp signal and the parameter estimation based on fractional Fourier transform (FRFT). The relationship between the FRFT and the Wigner-Ville distribution (WVD) is investigated and the performance of the new approach is analyzed both in the computation complexity and the resolution in the fractional Fourier domain.
