This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Pricipal Investigator's (PI's) team will develop new and improved instrumentation and infrastructure for the existing Owens Valley Solar Array (OVSA), and thereby create a major university-based facility serving a broad scientific community. The team will upgrade OVSA from its current complement of 7 antennas to a total of 15, with the addition of 8 new antennas. They will also replace existing OVSA control systems, wiring, and signal processing systems with modern, more capable, and more reliable electronics using new technologies. The project will result in a world-class facility for scientific research at microwave radio frequencies, focused on space weather physics and solar astronomy. Solar radio emission is very sensitive to the physics of space weather processes. The enhanced OVSA facility will provide key diagnostic observations of the magnetic and thermal structure of the solar atmosphere, the release of magnetic energy in the corona, and the space weather consequences of solar activity. This effort will provide the scientific community with new and powerful tools for radio astronomy in general, as well as a unique combination of spatial, spectral, and temporal resolution to exploit radio diagnostics of the Sun beyond what has previously been possible. The improved facility will support the university community by providing open data access and software tools for radio data analysis, and by exploiting data sets and analysis techniques used in on-going solar research in non-radio wavelength bands. The PI's team will invoke a rich heritage of radar design work to accomplish a wide range of science objectives that has been thoroughly vetted by the National Research Council of the National Academy of Sciences. The project will provide jobs to US small industry and to the local economy, and will offer technical training and scientific research experience for students, as well as young scientists and engineers. This development effort will provide trainees with much-needed instrumental expertise in the fields of broadband radio frequency engineering, high-speed digital electronics and signal processing, and high performance computing. The project includes well-integrated education and training plans for undergraduate and graduate students, as well as for post-doctoral researchers and entry-level engineers. The instrumentation and software developed by this project will provide new tools for classroom use, and will enlarge the base of researchers who will be able to apply interferometric imaging techniques and radio emission physics to studying key problems in solar physics, space weather physics, and astrophysics. The PI expects that new discoveries enabled by the new OVSA facility will help us improve the reliability of our technological systems on Earth and in space.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。 Pricipal调查员（PI）团队将为现有的Owens Valley Solar Array（OVSA）开发新的和改进的仪器和基础设施，从而创建一个基于大学的主要设施，为广泛的科学社区提供服务。该团队将将OVSA从目前的7天天线升级到总共15个，并增加了8个新天线。他们还将使用新技术替换现有，功能更高且更可靠的电子产品的现有OVSA控制系统，接线和信号处理系统。该项目将在微波无线电频率上建立世界一流的科学研究设施，该设施的重点是太空天气物理和太阳天文学。太阳能无线电发射对太空天气过程的物理学非常敏感。增强的OVSA设施将对太阳大气的磁性和热结构，电晕中的磁能释放以及太阳能活动的太空天气后果提供关键的诊断观察。这项工作将为科学界提供一般的射电天文学的新的和强大的工具，以及空间，光谱和时间分辨率的独特组合，以利用太阳的无线电诊断超出以前的可能性。改进的设施将通过提供无线电数据分析的开放数据访问和软件工具，并利用用于非Radio波长频段正在进行的太阳能研究中的数据集和分析技术来支持大学社区。 PI的团队将援引丰富的雷达设计工作遗产，以实现各种科学目标，这些目标已由国家科学院国家研究委员会彻底审查。该项目将为美国的小工业和当地经济提供就业机会，并将为学生以及年轻的科学家和工程师提供技术培训和科学研究经验。这种开发工作将为受训者提供急需的工具专业知识，该领域在宽带射频工程，高速数字电子和信号处理以及高性能计算领域的领域。该项目包括针对本科生和研究生的全面教育和培训计划，以及博士后研究人员和入门级工程师。该项目开发的仪器和软件将为课堂使用提供新的工具，并将扩大研究人员的基础，这些研究人员将能够应用干涉成像技术和无线电排放物理学来研究太阳能物理学，太空天气物理学和天体物理学的关键问题。 PI期望新的OVSA设施实现了新的发现，将有助于我们提高地球和太空中技术系统的可靠性。
