| Abstract | 随着射电天文研究的不断深入,科学家对望远镜分辨率和灵敏度的要求也不断提高,同时要求望远镜具有更宽的观测波段。单口径望远镜低频波段用主焦点接收,馈源尺寸可以更紧凑。而为了不影响双反射面天线次焦点的馈电功能,主焦点馈源的放置及换馈方案必须高效合理。本文以拟建于新疆奇台的110m口径全可动射电望远镜(QTT)为研究对象,以意大利SRT 64m和德国Effelsberg 100m射电望远镜为参考对象,对两种方案应用于QTT的可行性进行分析,并提出一种新的利用线性模组进行主焦馈源快速切换的新型方案。我们进行了直线模组机构的建模和仿真,并对口径面信号遮挡进行了分析,结果表明此方案能有效满足望远镜工作需求。 |
| Other Abstract | With the rapid development of radio astronomy research,the requirements to the sensitivity and resolution of telescopes,as well as wider observing band,constantly grow. The low frequency receivers are usually installed at the primary focus of the telescope so that the feed horns are smaller and lighter. The switching system of prime focus receivers must be effective and compact to avoid affecting normal use of the receivers on the secondary focus. A steerable 100m aperture radio telescope is supposed to be built in Qitai,Xinjiang ( QiTai radio Telescope,QTT) . This paper introduces a new solution of the switching system for the QTT primary focus receivers by using a linear module. Through the modeling and simulation of this scheme,and analyzing of the aperture interception to the observing signals,it is shown that our design well satisfies the efficiency requirement of QTT. |
