文摘This paper presents two modified discrete chirp Fourier transform (MDCFT) schemes. Some matched filter properties such as the optimal selection of the transform length, and its relation-ship to analog chirp-Fourier transform are studied. Compared to the DCFT proposed previously, theo-retical and simulation results have shown that the two MDCFTs can further improve the chirp rate reso-lution of the detected signals.
