Using machine learning for the detection of radio frequency interference

Research output: Chapter in Book/Conference paperConference paper

Abstract

Radio Astronomy, by its very nature, detects extremely faint cosmic radio signals and is therefore very susceptible to Radio Frequency Interference (RFI). We present some initial results of our work to identify RFI using a Machine Learning (ML) based approach. The data is taken from VLBI observations data from three well separated observatories in Australia: ATCA, Parkes and Mopra; and we work with the 2-bit data directly from the telescopes. Our approach uses a Generative Adversarial Network (GAN) and an autoencoder to perform unsupervised machine learning on the data.

OtherAP-RASC is a triennial event that brings together radio science specialists from all over the world, especially from the Asia Pacific region, covering all aspects of radio science across URSI’s ten commissions. This includes aspect of radio science related to metrology, radio propagation and communications and signal processing, electronics, photonics, electromagnetic interference, remote sensing, waves in plasma, radio astronomy and applications in biology and medicine. The main objective of the Conference is to review current trends in research, present new discoveries and make plans for future research work or for specific projects, especially where it seems desirable to arrange for cooperation on an international scale. The AP-RASC 2019 features committee meetings, technical sessions, workshops, general lectures as well as an exhibition of products related to radio science. An equally important objective is also to encourage scientific exchange and fellowship amongst industry colleagues and professionals globally. This conference will be an occasion for delegates to make new acquaintances and strengthen existing friendships
