This paper presents the quantitative analysis of signal-to-noise ratio (SNR) for the local polynomial Fourier transform (LPFT) used for application of inverse synthetic aperture radar (ISAR) imaging. The relationship between the LPFT and Wigner-Ville distribution (WVD) is derived and theoretical analysis on the SNR achieved by using the LPFT is given. Comparisons on the SNR performances achieved by...
In this paper the local polynomial Fourier transform is introduced. Theoretical analysis and comparisons on the SNR ratio achieved by using the local polynomial Fourier transform, the short time Fourier transform, and the Fourier transform are presented to illustrate the merit of the local polynomial Fourier transform. Improved performance for radar imaging using the local polynomial Fourier transform...
