No, but I know that radio astronomers do this.

I have done FFT with CUDA. As long as you can keep the data inside the
GPU for long enough, you can get pretty nice performance. I have
measured over 100 GFLOPS on FFT with a $300 Nvidia GPU. I haven't
tried yet with my new 480 GTX, but it should be even faster.
