CEDAR: Transmitter and Receiver Upgrade for the Urbana Medium Frequency (MF) Radar Under the CEDAR Program

要求拨款更换厄巴纳中频雷达的发射机，该雷达是研究中大气动力学的重要贡献者。一个新的单元将由计算机控制，断电后自动复位，更容易维护学生。此外，还要求提供经费，以便用四个新装置取代现有的单一接收器。这项工作很重要，因为厄巴纳雷达将有助于提高对平均风和潮汐的纵向差异的理解。

Funds are requested to replace the transmitter for the Urbana medium frequency (MF) radar, an important contributor to the study of middle atmosphere dynamics. A new unit will be computer controlled, automatically reset after a power failure, and more easily maintained by students. In addition, funds are also requested for the purpose of replacing the single existing receiver with four new units. This work is important because the Urbana radar will contribute to the improved understanding of longitudinal differences in mean winds and tides.
