Calibration and Stokes Imaging with Full Embedded Element Primary Beam Model for the Murchison Widefield Array
M. Sokolowski, T. Colegate, A. T. Sutinjo +22
The Murchison Widefield Array (MWA), located in Western Australia, is one of the low-frequency precursors of the international Square Kilometre Array (SKA) project. In addition to…
Revisiting Hybrid Interferometry with Low-Frequency Radio Astronomy Arrays
Adrian T. Sutinjo, Daniel Ung, Tim M. Colegate +3
Radio interferometry most commonly involves antennas or antenna arrays of identical design. The identical antenna assumption leads to a convenient and useful mathematical simplific…
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…
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…
Realisation of a low frequency SKA Precursor: The Murchison Widefield Array
S. J. Tingay, R. Goeke, J. N. Hewitt +56
The Murchison Widefield Array is a low frequency (80 - 300 MHz) SKA Precursor, comprising 128 aperture array elements distributed over an area of 3 km diameter. The MWA is located…
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…
