Hi,

it was a bit hidden in my yesterdays post:

Fast Fourier transforms for nonequispaced data, Potts et. al.
http://www-user.tu-chemnitz.de/~potts/nfft/
http://www-user.tu-chemnitz.de/~potts/nfft/polar.php

Fast and Accurate Polar Fourier Transform, Averbuch et. al.
http://www.cs.tau.ac.il/~amir1/PS/Polar_Paper_New.pdf
http://www.math.umn.edu/~focm/c_/Elad.pdf

NFFT is actually a c/c++ program that can do it (polar transform is an
example of how one can use NFFT), the others have a Matlab program as far
as I know...

Would be awesome if somebody wants to rewrite it for Java :) I would offer
my help for that...

All the best,
Stephan
