The Operation of the Cambridge One-Mile Diameter Radio Telescope

Abstract

The new radio telescope at Cambridge uses the technique of synthesis to produce an aperture one mile in diameter, giving beamwidths of 80″ and 23″ arc at its two observing frequencies of 408 and 1407 Mc/s. This paper describes how the telescope may be used (i) to obtain accurate positions of point sources, (ii) to determine the angular structure of extended sources, and (iii) to make a complete survey of very weak radio sources over a limited area of sky.
