Omniscopes: Large area telescope arrays with only N logN computational cost
We show that the class of antenna layouts for telescope arrays allowing cheap analysis hardware (with correlator cost scaling as Nlog N rather than N[superscript 2] with the number of antennas N) is encouragingly large, including not only previously discussed rectangular grids but also arbitrary hie...
