How does a radio telescope array work? A radio telescope is made up of a dish, or reflecting surface (the most visible part of the telescope), and antennas/receivers, which can be positioned to collect radio waves from different areas on the sky. The dish focuses radio waves onto antennas, which are sensitive to certain wavelengths.
Why are radio telescopes in arrays? An array is a group of several radio antennas observing together creating — in effect — a single telescope many miles across. As a first step, NRAO built the Green Bank Interferometer to learn and develop best communications, correlation, and atmospheric correction practices.
How does a radio observatory work? Here’s how it works: Two radio telescopes observe the same radio source. The telescopes are a known distance apart on the ground. The radio waves coming from the source will therefore arrive at one telescope at a slightly different time than the other.
What does a radio telescope detect? radio telescope, astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation between wavelengths of about 10 metres (30 megahertz [MHz]) and 1 mm (300 gigahertz [GHz]) emitted by extraterrestrial sources, such as stars, galaxies, and quasars.
