【摘要】：平方公里阵SKA(Square Kilometre Array)是计划建造的世界最大综合孔径射电望远镜,致力于回答宇宙起源和基本力等问题.自1993年概念提出,全球已有20个国家67个科研机构的天文学家和工程师参与SKA预研究.中国在SKA发起、选址、工程概念及技术研发等方面起到了重要推进作用.目前SKA已进入建设准备阶段,包括中国在内的许多国家正在进行先导天线、相位阵馈源等SKA关键技术试验研究.中国持续参与SKA国际合作,组建团队探索有限科学目标、致力于高精度轻型天线设计与工艺研究、宽频带大视场接收机技术研究,将跨越式提升我国天文学和技术水平、我国工程和制造业水平,实现国际重大科学工程的"中国创造"里程碑.其可行性已通过多方分析和论证,SKA是中国参与21世纪国际重大科学工程千载难逢的机遇.
[Abstract]:SKA(Square Kilometre Array is the world's largest synthetic aperture radio telescope designed to answer questions about the origin of the universe and fundamental forces. Astronomers and engineers from 67 scientific research institutes in 20 countries have participated in SKA pre-research. China has played an important role in promoting SKA initiation, site selection, engineering concept and technology research and development. At present, SKA has entered the stage of construction preparation. Many countries, including China, are conducting pilot antennas, phase array feeders, and other key SKA technologies. China continues to participate in international SKA cooperation and form teams to explore limited scientific goals. Dedicated to high precision light antenna design and technology research, wide band large field of view receiver technology research, will leapfrog to improve the level of astronomy and technology, China's engineering and manufacturing level, The feasibility of realizing the milestone of "China creation" in international major scientific projects has been proved by various analysis and demonstration that SKA is a rare opportunity for China to participate in major international scientific projects in the 21st century.
