HERA RFI Detection (Hydrogen Epoch of Reionization Array (HERA))
Introduced by Mesarcik et al. in Learning to detect RFI in radio astronomy without seeing it
This dataset contains simulated and expert-labelled spectrograms from two radio telescopes: the Hydrogen Epoch of Reionization Array (HERA) in South Africa and the Low-Frequency Array (LOFAR) in the Netherlands. These datasets are intended to test radio-frequency interference (RFI) detection schemes. This entry pertains to the HERA dataset specifically.
The HERA dataset is comprised of: - 560 Spectrograms and accompanying binary mask information. - Several copies of this dataset with classes of RFI sources removed for out-of-distribution testing.
This dataset has been preprocessed into 512 x 512 x 1 images. The low number of target pixels (RFI) proportional to the total data volume makes this dataset a useful test for RFI detection schemes in radio astronomy and, more generally, anomaly detection or semantic segmentation methods.
