Finally, the radar images are obtained by the inverse Fourier transform on the azimuth direction. Since the algorithm uses the property of the Chirp-Z transform processing the nonlinear modulation frequency signal, the processing procedure is simplified and the imaging precision is greatly improved. ...
By adjusting the parameters M, A, and W, the chirp z-transform algorithm can efficiently compute the z-transform of a sequence with arbitrary starting and ending positions, as well as any sampling interval in the z-plane, and obtain an output sequence of length M. Consequently, the chirp ...

This paper shows that the inverse chirp z-transform (ICZT), which generalizes the inverse fast Fourier transform (IFFT) off the unit circle in the complex plane, can also be used with chirp contours that perform partial or multiple revolutions on the unit circle. This is done as a special...

To solve the above problems, in this paper, a multi-surface wavelength-shifting interferometry algorithm based on the Chirp-Z transform (MWI-CZT) with local spectral denseness is developed. The proposed MWI-CZT method mainly consists of three steps: (1) Considering the sampling theorem, the anal...
