Radio Astronomy Receivers

IEEE Transactions on Military Electronics, 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.

The faint radio sky: radio astronomy becomes mainstream

Astronomy and Astrophysics Review, 2016
Radio astronomy has changed. After years of studying rare, mostly non-thermal sources, i.e. radio quasars and radio galaxies, it is now reaching such faint flux densities that it detects mainly star-forming galaxies and the more common radio-quiet active

Aperture 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
