The Murchison Widefield Array (MWA) is a low-frequency radio telescope operating between 80 and 300 MHz. It is located in one of the most radio quiet locations on the planet, the Murchison Radio-astronomy Observatory (MRO) in Western Australia. The MWA is the most sensitive low frequency radio telescope on the planet. This increased sensitivity and radio quietness introduces a problem with Radio Frequency Interference (RFI) from unexpected sources.
The Tom Price mine site is approximately 600km to the north of the MRO and runs daily trains of 230+ iron ore carriers, pulled by 2-4 locomotives. These produce RFI, which if characterised correctly, can, potentially, be removed from the original signal.
This project will take:
- observation data from the MWA archive
- and the GPS data from the Tom Price locomotives
and search for signatures of RFI from the locomotives.
