Algorithms for FFT Beamforming Radio Interferometers

Algorithms for FFT Beamforming Radio Interferometers

Radio interferometers consisting of identical antennas arranged on a regular lattice permit fast Fourier transform beamforming, which reduces the correlation cost fromω (n2) in the number of antennas toω(n log n). We develop a formalism for describing this process and apply this formalism to derive...
