The Miyun metre-wave aperture synthesis radiotelescope, working at frequency of 232 MHz, consists of an E-W array of 28 elements, each of 9 m aperture. 192 baselines are effected with a full coverage of the U-V plane (Fig. 2). The longest baseline is 1,164m. This instrument is designed for source survey and detection of peculiar sources in northern declinations. A set of observations completed in 2 × 12 hours gives a thermal noise limited sensititity of 0.05 Jy and a resolution of 3'8 × 3'8 csc δ. The field of view is 8° × 8°. This should enable us to complete an overall survey of the region δ >= + 30° within two years, and to carry out monitoring of selected areas.
Figures 1 and 2 show the main properties and general design of the instrument and Figures 3 and 4 give some preliminary results of sky mapping.
The following persons took part in the designing and making of the telescope: WANG Hong, Wang Xin-min, Wang Shou-guan, Liu Fu-you, Pu Ting-yi, Chen Hong-shen, Qiu Yu-hai, Yang Yi-pei, Pang Lei, Zhang Chun-lu, Zhang Guo-quan, Zhang Xi-zhen, Jin Tie-lin, Zheng Yi-jia, Zhao Hui-ping, Nan Ren-dong, Kang Lian-sheng, Bao Hong-qi, Wei Ming-zhi.
