Abstract
Based on the fractional Fourier transform, the fractional spectrum of non-uniformly sampled signal, which occurs in practical applications, has been analyzed and studied. Then the spectrum representation of a non-uniformly sampled chirp signal in the fractional Fourier domain has been derived. And the properties of fractional spectrum for non-uniformly sampled chirp signal have been investigated. The simulations are also proposed in the last to verify the correctness of the results.
