标题： Laboratory Exercises Using the Haystack VSRT Interferometer To Teach the Basics of Aperture Synthesis

摘要： 我们开发了一套大学水平的桌面实验室，可以使用干涉仪进行实验，利用卫星电视电子设备和紧凑型荧光灯作为微波信号源。 该干涉仪最初由麻省理工学院Haystack天文台开发，作为非常小型射电望远镜（VSRT）用于观测太阳，为学生提供了无线电干涉测量基础的动手实践经验。 这些实验室易于进行，并能直观地展示如何通过结合天线阵列的信号来揭示射电源结构的信息。 我们还开发了一套Java程序，称为“VSRTI绘图器”，可免费下载，以促进这些实验室的数据处理和分析。 显示英文摘要

摘要： We have developed a set of college level, table-top labs that can be performed with an interferometer using satellite TV electronics and compact fluorescent lamps as microwave signal sources. This interferometer, which was originally developed at the MIT Haystack Observatory as a Very Small Radio Telescope (VSRT) to observe the Sun, provides students with hands-on experience in the fundamentals of radio interferometry. These labs are easily performed and convey an intuitive sense of how combining the signals from an array of antennas reveals information about the structure of a radio source. We have also developed a package of java programs, called "VSRTI Plotter", which is available as a free-download, to facilitate the data processing and analysis of these labs.
