TL;DR: The Boolardy test array as discussed by the authors is a prototype of the Australian square kilometre array pathfinder telescope with a six-antenna interferometer, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously.
Journal ArticleDOI
Understanding instrumental Stokes leakage in Murchison Widefield Array polarimetry
Adrian Sutinjo,John David O'sullivan,John David O'sullivan,Emil Lenc,Randall B. Wayth,Shantanu Padhi,Peter J. Hall,Steven Tingay +7 more
TL;DR: In this paper, a simple model that accounts for interelement mutual coupling is presented which explains the prominence of Q leakage seen when the array is scanned away from zenith in the principal planes.
