An instrument used in astronomical research to study naturally occurring radio emission from stars, galaxies, quasars, pulsars, interstellar clouds, and other astronomical bodies between wavelengths of about 1 mm (300 GHz) and 10 m (30 MHz). At the short-wavelength end, the performance is limited by the opacity of the terrestrial atmosphere, and at the long-wavelength end by the opacity of the ionosphere.
