【摘要】：計劃在新疆奇臺建設(shè)的110米射電望遠(yuǎn)鏡(簡稱QTT)將位居國際一流大科學(xué)裝置之列,成為世界最大的全向可轉(zhuǎn)動射電望遠(yuǎn)鏡.QTT在引力波探測、黑洞發(fā)現(xiàn)、恒星形成、星系起源等基礎(chǔ)科學(xué)研究領(lǐng)域?qū)l(fā)揮重要作用,并可發(fā)展應(yīng)用于深空探測,如探月工程和火星、金星探測.QTT設(shè)計方案考慮多種科學(xué)目標(biāo)的需求,其關(guān)鍵技術(shù)包括:大口徑天線結(jié)構(gòu)設(shè)計技術(shù)、天線主動面技術(shù)、大慣量機(jī)架精密伺服控制技術(shù)、超寬帶饋源技術(shù)、低噪聲放大器技術(shù)、多波束接收技術(shù)等.QTT關(guān)鍵技術(shù)的突破與應(yīng)用,將促進(jìn)我國信息、精密機(jī)械加工和自動控制等工程技術(shù)領(lǐng)域的發(fā)展.QTT各系統(tǒng)建設(shè)將以自主創(chuàng)新為主,通過國際合作引進(jìn)和采用相關(guān)尖端技術(shù)完成.
[Abstract]:The 110m Radio Telescope (QTT), which is planned to be built in Qitai, Xinjiang, will rank among the world's top scientific devices, becoming the world's largest omnidirectional rotatable radio telescope. QTT detects gravitational waves, black holes and stars. Basic scientific research, such as the origin of galaxies, will play an important role and can be developed for use in deep space exploration, such as lunar exploration and Mars, Venus exploration. QTT design plans take into account the needs of a variety of scientific objectives. The key technologies include: large aperture antenna structure design technology, antenna active surface technology, large inertia frame precision servo control technology, ultra-wideband feed technology, low noise amplifier technology, The breakthrough and application of key technologies such as multi-beam receiving technology. QTT will promote the development of engineering technology such as information, precision machining and automatic control in China. The construction of QTT systems will be dominated by independent innovation. Through international cooperation to introduce and use relevant cutting-edge technology to complete.
