摘　　要：本文是专题“面向天文、物理和多个工科专业的射电望远镜实验平台”上篇,内容包括望远镜基本参数和实验设计,以及天文源跟踪、数据文件生成两个实现望远镜天文观测功能的选做实验。太阳是距离我们最近的较强天文射电源,本文基于实例介绍了太阳射电流强时域变化实验。With the development of astronomical observation equipment and the expansion of astronomical education in China,how to conduct practical teaching in astronomy has become a challenge for astronomy departments and physics departments with astronomy majors in colleges and universities.To adapt students to the rapid development of national major scientific installations,the School of Physics and Astronomy at Sun Yat-sen University(SYSU)completed the construction of a 3.2-meter teaching radio telescope in 2021.Through three years of exploration in the course of“Astronomical Observation Practice”,the goal of helping students understand the structure and principles of radio telescopes,as well as the basic processes of astronomical observation,has been achieved.At the same time,we realize that this experimental platform can help students learn basic physical concepts such as spectral line broadening,error analysis and control,and time-frequency analysis of signals in practice.Students need to apply multidisciplinary knowledge to complete experiments,making it suit-able to open to general physics and engineering majors.This special topic is prepared in two parts to introduce the experiments on SYSU 3.2-meter radio telescope,including telescope pointing control,generation of standard astronomical data,and specific time-domain and fre-quency-domain astronomical observation experiments,that is,experiment of solar radio flux intensity time-domain variation and the observation experiment of neutral hydrogen spectral lines.They are noted as a reference for us and other schools to carry out practical astronomy teaching,and for the radio telescope to serve as a platform for elective experiments in univer-sity physics.This is the first part of the special topic,in which the basic parameters of the telescope as well as the design of students experiments are introduced.It also has specific contents of two experiments that make the telescope functional for astronomical observations,i.e.,astro-nomical source tracking and data file
