TL;DR: In this article, the authors present a wide-field interferometric imager that uses the w-stacking algorithm and can make use of the W-snapshot algorithm, which is an order of magnitude faster than w-projection, as well as being capable of full-sky imaging at full resolution with correct polarization correction.

TL;DR: The Murchison Widefield Array is a dipole-based aperture array synthesis telescope designed to operate in the 80-300 MHz frequency range, capable of a wide range of science investigations but initially focused on three key science projects: detection and characterization of three-dimensional brightness temperature fluctuations in the 21 cm line of neutral hydrogen during the epoch of reionization.
