Physics Today, 1950
Until recently astronomy was restricted to the visual band of the electromagnetic spectrum, and to wavelengths near to the visual band. Our immense store of astronomical knowledge has been obtained from observations made in a band of about four octaves of the spectrum, although measuring techniques are available for about forty octaves.

Radio Astronomy (Radio Astronomie)
1991Aperture Synthesis Telescopes — Commissioning tests and observations have been made using three antennas in the Australia Telescope (AT), spaced up to 2km apart, and the first image of a radio source observed at 6cm was produced in 1989. The IRAM millimeter array in France comprizing three 15-m antennas has been commissioned at 3mm. A fourth antenna is

IEEE Transactions on Antennas and Propagation, 1964
A general survey of the principles of radio astronomy receivers is presented. System noise temperature, the sensitivity of different receiver types, and the calibration of receivers are studied. A total-power receiver is analyzed as a basic radio telescope receiver and.

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 ...

Introduction to Radio Astronomy
Physics Bulletin, 1967R. C. Jennison New York: Philosophical Library Inc. 1967 Pp. viii + 160. Price $4.75. In the last twenty years radio astronomy has developed into one of the most fascinating areas and growing points of modern scientific research. There have already appeared several popular books on the subject, also one or two text books of an advanced nature, but ...
