Dominion Radio Astrophysical Observatory (DRAO) Frequency Interference & Spectrum Management
May 14 at 11:00 am - 12:00 pm
Free
The Irving K. Barber Faculty of Science and the Dominion Radio Astrophysical Observatory (DRAO) are pleased to present a joint seminar on Radio Frequency Interference (RFI) and Spectrum Management in Radio Astronomy.
About the Talk
Radio frequency interference (RFI) is the most significant threat to the scientific performance of radio astronomy facilities. Modern radio observatories consist of complex, integrated systems with ultra‑wideband receivers, all of which must function properly within a shared electromagnetic environment—without generating or experiencing harmful interference.
At the Dominion Radio Astrophysical Observatory (DRAO), telescope protection and interference limits are defined through the DRAO RFI/EMC Standard, based on internationally accepted methods from the International Telecommunication Union (ITU) Recommendation ITU‑R RA.769. Managing RFI within the observatory typically involves Electromagnetic Compatibility (EMC) Control Plans, while external interference—from terrestrial, airborne, or space‑based sources—is addressed through international spectrum management and national participation in ITU radio regulations.
This presentation offers a high‑level overview of RFI and spectrum management considerations at DRAO and at radio observatories worldwide.
Speaker
Presenter: Dr. Braam Otto
Dr Braam Otto is the Principal Research Officer from National Research Canada. Dr. Otto recently began as a Research Officer at the Dominion Radio Astrophysical Observatory, focusing on radio frequency interference and spectrum management. He works on both engineering related to detection and mitigation of interference and statistical analysis of RFI data.
