Characterization of a Low-Frequency Radio Astronomy Prototype Array in Western Australia
A. T. Sutinjo, T. M. Colegate, R. B. Wayth +12
We report characterization results for an engineering prototype of a next-generation low-frequency radio astronomy array. This prototype, which we refer to as the Aperture Array Ve…
The impact of the ionosphere on ground-based detection of the global Epoch of Reionisation signal
Marcin Sokolowski, Randall B. Wayth, Steven E. Tremblay +7
The redshifted 21cm line of neutral hydrogen (Hi), potentially observable at low radio frequencies (~50-200 MHz), is a promising probe of the physical conditions of the inter-galac…
Antenna array characterization via radio interferometry observation of astronomical sources
T. M. Colegate, A. T. Sutinjo, P. J. Hall +12
We present an in-situ antenna characterization method and results for a "low-frequency" radio astronomy engineering prototype array, characterized over the 75-300 MHz frequency ran…
BIGHORNS - Broadband Instrument for Global HydrOgen ReioNisation Signal
M. Sokolowski, S. E. Tremblay, R. B. Wayth +12
The redshifted 21cm line of neutral hydrogen (HI), potentially observable at low radio frequencies (~50-200 MHz), should be a powerful probe of the physical conditions of the inter…
Understanding Instrumental Stokes Leakage in Murchison Widefield Array Polarimetry
Adrian Sutinjo, John O'Sullivan, Emil Lenc +4
This paper offers an electromagnetic, more specifically array theory, perspective on understanding strong instrumental polarization effects for planar low-frequency "aperture array…
Square Kilometre Array station configuration using two-stage beamforming
Aziz Jiwani, Tim Colegate, Nima Razavi-Ghods +3
The lowest frequency band (70 - 450 MHz) of the Square Kilometre Array will consist of sparse aperture arrays grouped into geographically-localised patches, or stations. Signals fr…
