Non-Uniform Fourier Transform
The non-uniform Fourier transform is a variant of the Fourier transform used for non-uniformly sampled signals, in which sample positions in frequency space are uneven. It is commonly applied in scenarios such as synthetic aperture radar.

The study examined a classification task inspired by synthetic aperture radar (SAR), a task that naturally has the structure of a non-uniform Fourier transform: the evaluation frequencies are determined by geometry, and the sampling positions are determined by the radar trajectory.
