Low-frequency radio astronomy engineering in Western Australia

I will discuss low-frequency radio astronomy engineering efforts underway in Western Australia. We carry out this work through the International Centre for Radio Astronomy Research (ICRAR)/Curtin University. The frequency range of interest is ∼50 to ∼350 MHz, which is the Low-Frequency Square Kilometre Array (SKA-Low) frequency band. I will describe recent and current work in the Murchison Widefield Array (MWA), the Engineering Development Array (EDA) and the Aperture Array Verification System (AAVS). I will also discuss engineering research work in antenna array beam modelling and low-noise amplifier (LNA) noise measurement for low-frequency radio astronomy.
