Inferring radio beams from sparse sampling patterns: a case study with the Murchison Widefield Array
Michael J. Wilensky, Aman Chokshi
Accurate primary-beam models are essential for high-dynamic-range radio experiments, particularly searches for the redshifted 21-cm signal from the Epoch of Reionisation, where bea…
Inverting and Up-channelizing Critically-Sampled Polyphase Filter Banks
Stephen Fay, Mohan Agrawal, Hsin Cynthia Chiang +3
Polyphase filter banks (PFBs) are widely used to channelize digitized time-domain data in real time. However, applications such as radio astronomy often require higher spectral res…
Continuous Ultra-Low-Frequency Solar Radio Monitoring with ALBATROS from the High Arctic
Aman Chokshi, Mohan Agrawal, Christopher Barbarie +18
In the Canadian High Arctic, nearly five months of continuous daylight enable uninterrupted low-frequency solar monitoring. We present the first solar science results from the Arra…
Drone-Based Antenna Beam Calibration in the High Arctic
Lawrence Herman, Christopher Barbarie, Will Tyndall +17
Precision calibration is a critical requirement for future ultra-low-frequency observations of the early universe. The Array of Long Baseline Antennas for Taking Radio Observations…
