New Wide-band Digital Technology and Interference Excision for Radio Astronomy

射电天文学让我们看到了宇宙中不可见的一面，这样做使我们能够研究各种各样的主题，如恒星和行星的诞生地，黑洞和爱因斯坦的理论，以及宇宙的命运。然而，这些领域的研究正变得越来越困难，因为我们日常生活中依赖的许多技术，如手机和无线互联网，也会发射无线电波。它们可以掩盖微弱的宇宙信号。该项目将利用尖端数字技术开发下一代射电望远镜灵敏探测器。它还将通过区分人造和宇宙无线电信号，提高我们与非天文学家共享无线电频谱的能力。该项目将为第一代大学生提供教育经验。新的模拟和数字技术使处理更大的无线电带宽成为可能;但这是因为无线电频谱正在被越来越多的商业，民用和私人使用。该项目将为射电天文学开发下一代数字技术。它将为世界上最灵敏的射电望远镜上更稳定和灵敏的宽带宽、高数据率仪器奠定基础。与此同时，该项目将开发新技术，用于识别和消除人造无线电信号，同时保护科学数据。该项目包括为第一代大学生提供暑期实习机会。学生将帮助建立一个人造无线电信号目录，同时学习有价值的专业和技术技能。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

Radio astronomy lets us see an otherwise invisible side of the Universe, and in doing so allows us to study topics as diverse as the birthplaces of stars and planets, black holes and Einstein's theories, and the very fate of the Universe. Research in these areas is becoming increasingly difficult, however, because so much of the technology that we rely on in our daily lives, like cell phones and wireless internet, also emit radio waves. These can overwhelm weak cosmic signals. This project will make use of cutting edge digital technology to develop the next generation of sensitive detectors for radio telescopes. It will also improve our ability to share the radio spectrum with non-astronomers by differentiating between human-made and cosmic radio signals. This project will provide an educational experience for first-generation college students. It will give them a hands-on research experience and the skills needed for future success in technical fields.New analog and digital technology is making it feasible to process ever larger radio bandwidths; but this comes as the radio spectrum is seeing increasing commercial, civil, and private use. This project will develop the next generation of digital technology for radio astronomy. It will lay the foundation for more stable and sensitive wide-bandwidth, high data-rate instruments on the world's most sensitive radio telescopes. At the same time, the project will develop new techniques for identifying and removing human-made radio signals while preserving scientific data. The project includes a summer internship for first-generation college students. Students will help to build a catalog of human-made radio signals while learning valuable professional and technical skills.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
