The One-Mile Telescope at the Mullard Radio Astronomy Observatory (MRAO) is an array of radio telescopes (2 fixed and 1 moveable, fully steerable 60-ft-diameter parabolic reflectors operating simultaneously at 1407 MHz and 408 MHz)〔(The operation of the Cambridge one-mile telescope ), Monthly Notices of the Royal Astronomical Society, Vol. 134, p.87〕 designed to perform aperture synthesis interferometry. == History == The One Mile Telescope was completed by the Radio Astronomy Group of Cambridge University in 1964. The telescope was used to produce the 5C catalogue of radio sources. Observations with larger incremental spacings were used to observe individual radio sources with unprecedented sensitivity, angular resolution, and image quality. These surveys required intensive use of inverse Fourier Transforms, and were made possible by development of a new generation of computers such as the Titan. In 1971, Sir Martin Ryle described why, in the late 1950s, radio astronomers at MRAO decided on the construction of the new One Mile telescope: "Our object was twofold. First we wanted to extend the range of our observations far back in time to the earliest days of the Universe, and this required a large increase in both sensitivity and resolution. With greater resolution we hoped that we might be able to draw radio maps of individual radio sources with sufficient detail to give some indication of the physical processes which brought them into being." One of the One Mile Telescope dishes was temporarily used to improve the resolution of MERLIN (then MTRLI) from 1987 until Autumn 1990.〔(【引用サイトリンク】 title=MERLIN: The 32-metre Telescope )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「One-Mile Telescope」の詳細全文を読む スポンサード リンク
