论文摘要
我们已经设计了一个名为Bose Horn天线射电望远镜（Bharat）的低成本射电望远镜系统，以检测我们的银河系中的21 cm氢线发射。该系统正在印度天文学和天体物理学（IUCAA）的无线电物理实验室（RPL）用于实验室课程，并培训学生和老师。它也是几所大学和大学实验室课程的一部分。在这里，我们介绍了一种高效，易于构建和具有成本效益的双模式锥形角的设计，并描述了校准程序。我们还提供了一些使用望远镜获得的模型观察数据，以促进本科或研究生课程的实验室课程中轻松合并该实验。我们以Acharya Jagadish Chandra Bose的名字命名了天线，纪念无线电科学的先驱和一位杰出的老师，他启发了几位世界著名的科学家。
We have designed a low-cost radio telescope system named the Bose Horn Antenna Radio Telescope (BHARAT) to detect the 21 cm hydrogen line emission from our Galaxy. The system is being used at the Radio Physics Laboratory (RPL), Inter-University Centre for Astronomy and Astrophysics (IUCAA), India, for laboratory sessions and training students and teachers. It is also a part of the laboratory curriculum at several universities and colleges. Here, we present the design of a highly efficient, easy to build, and cost-effective dual-mode conical horn used as a radio telescope and describe the calibration procedure. We also present some model observation data acquired using the telescope for facilitating easy incorporation of this experiment in the laboratory curriculum of undergraduate or post-graduate programs. We have named the antenna after Acharya Jagadish Chandra Bose, honoring a pioneer in radio-wave science and an outstanding teacher, who inspired several world renowned scientists.
