The Department is purchasing a 4.5 meter radio antenna and motors, to be used in an instructional radio telescope. Electronics and test equipment from a recently decommissioned radio telescope are being used to complete the system. The telescope is capable of a wide variety of radiometric and spectrometric observations. Projects include measurements of the flux density and spectra of extragalactic radio sources and galactic H II regions, observations of neutral hydrogen in the galaxy, and study of the effects of the atmosphere on radio wave propagation. This instrument benefits the education of a wide variety of undergraduate students. It is used as a demonstration device in a large introductory course for nonscience students. Students in the freshman course for physics and astronomy majors use the telescope in several laboratory experiments. Finally, the radio telescope is the centerpiece of a laboratory for upper level undergraduate and graduate students in astronomy, physics, and engineering. In this course students are taught the rudiments of instrumentation in radio astronomy and radiophysics.

该部门正在购买 4.5 米射电天线和电机，用于教学射电望远镜。 最近退役的射电望远镜的电子设备和测试设备正在被用来完善该系统。 该望远镜能够进行各种辐射和光谱观测。 项目包括测量河外射电源和银河H II区域的通量密度和光谱、观测银河系中的中性氢以及研究大气对无线电波传播的影响。 该仪器有利于各类本科生的教育。 它被用作非科学学生的大型入门课程中的演示设备。 物理和天文学专业的新生课程的学生在几个实验室实验中使用了望远镜。 最后，射电望远镜是天文学、物理学和工程学高年级本科生和研究生实验室的核心。 在本课程中，学生将学习射电天文学和放射物理学仪器的基础知识。
