A new meter-wave survey of sky region north of declination +30° is carried out with the Miyun 232 MHz Synthesis Radio Telescope(MSRT). The instrument, observation and some new imaging techniques are briefly described in this paper. As first result, two 8° × 8° regions centred respectively at α : 00h41m, δ: 41°12′ and α: 07h00m, δ: 35°00′ were observed and reduced. On the average 4 – 5 sources per square degree are recorded with position accuracy of 5′ / S(Jy). The accuracy of flux determination is limited by background fluctuation which is about 30 mJy. The catalogue is complete for sources with flux larger than 0.25 Jy.
