XU Hui-fa · Journal of Naval Aeronautical and Astronautical University · 2010
A self-adaptive nonuniformly sampled method was presented in this paper,and the fractional spectrum of nonuniformly sampled signal was analyzed and studied based on fractional Fourier transform,then the digital spectrum expression of this kind of nonuniformly sampled signal in the fractional Fourier domain had been derived.Further,the fractional spectrum expression of nonuniformly sampled Chirp signal was derived.In the end,the results were verified by simulations.
