Abstr act The Chirp-Z transform (CZT) algorithm is a digital signal processing algorithm, it is applicable to the general case calculating limited width of the Ztransform along the spiral curve.The CZT is more flexible than the Fast Fourier transform (FFT) in calculating the frequency spectrum, so it is used in various fields such as radar ranging, power prediction and so on.But the implementation steps of the algorithm are difficulty to understand.This paper introduces the realizing process of CZT based on MATLAB GUI, Including the computational path of CZT, the main sequences and their simulation of CZT and FFT, it also presents the main program and simulation.
