Fast Fourier Transform Telescope (FFT Telescope) is the name of a 2008 telescope-concept for a Radio Telescope array to observe 21cm Lines. A regular grid of antennas would collect the signal to be processed in real time using Fast Fourier Transform-processing to simulate a larger Aperture telescope, a kind of Aperture Synthesis. http://arxiv.org/abs/0805.4414 Referenced by: Software Telescope |
