Direction of Arrival (DoA) Estimation in Radio Astronomy

-- Alen | August 25, 2020

Question:

Hello,
I’m wondering if there are any applications for Direction of Arrival (DoA) estimation in radio telescopes. Can you give some examples (if any).
Thank you

-- Alen

Answer:

In fact, Direction of Arrival (DoA) is a fundamental aspect of how all radio telescopes collect data. Essentially all radio telescope measurements, whether they employ a single antenna, a single antenna with a multi-pixel detector, or an array of radio telescopes, use DoA to interpret the measurements made and associate those measurements to the astrophysical objects under study.

The National Radio Astronomy Observatory is a facility of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
