Application of the Fractional Fourier Transform and S-Method in Doppler Radar Tomography

Abstract

Doppler radar tomography is a technique which uses only the Doppler profiles of a rotating target as projections in two-dimensional radar tomography to obtain an image of the target. The work demonstrates, for the first time, the application of the fractional Fourier transform and the S-Method in improving the image resolution. The performance is shown to be significantly better than that available with traditional Fourier transform-based methods.
