Radio Astronomy and Radio Telescopes
2010An astronomical object somewhere in the Planetary System, the Galaxy, a Cluster of Galaxies, or far out in the Universe may generate radio waves by one or the other physical process (a topic of Astrophysics). If the radio emission is generated inside the object, some of the radio waves propagate through the object until they may leave the radio source ...

The Australian radio-telescope
Astrophysics and Space Science, 1986A large synthesis radio telescope is under construction in Australia at a cost of $A 30.7million. In comprises a 6 km-long ‘compact array’ of 22 m antenna at Culgoora and a ‘long baseline array’ of 319 km, achieved by adding another 22 m antenna near Coonabarabran and the existing 64 m antennae at Parkes.

Radio-Telescope Antenna Parameters
IEEE Transactions on Military Electronics, 1964Principal antenna parameters which are useful in characterizing the electrical performance of radio-telescope antennas are defined and the relations between them are established. The application of these parameters to radio astronomical measurements is discussed.

In the last 30 years radio telescopes have given astronomers an entirely new picture of the universe. Radio astronomy has a distinguished record of discovering things not only unknown, but unsuspected. The record stretches from the original discovery in the 1930's that astronomical objects gave off radio waves (SNL: 6/3/33, p.

Conventional methods can no longer satisfy many observational requirements in radio astronomy. New principles are being applied in a range of instruments designed for specific purposes; some of these are discussed and contrasted in this article, which is based on a lecture given at an Ordinary Meeting at Savoy Place on the 27th October 1960.

Single antenna small radio telescopes, 30-m diameter and smaller, are often overshadowed by the few large dishes and multiple antennae arrays. Contemporary emphasis in radio astronomy is the construction of large antennae and multiple antennae arrays. Of course, the obvious reasons include greater flux sensitivity and improvement of spatial resolution.

Lincoln Laboratory's new Haystack Microwave Research Facility, located on Haystack Hill in Tyngsboro, Mass., was formally dedicated on October 8. The installation will serve as a radio telescope, a ground terminal for space communications, and a tracking and measurements radar.

Physics Today, 1962
Tests of the new Australian radio telescope at Parkes, New South Wales, have indicated that the instrument performs as sensitivitely as its planners had hoped. Since October 31 of last year, when it was formally commissioned, the telescope has been recording up to three times as many radio sources in a given part of the sky as were known to exist ...
