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

请求提供资金，以更换Urbana号的发射机 中频（MF）雷达，研究的重要贡献者 中层大气动力学 一个新的单位将是计算机 控制，电源故障后自动复位，等等 容易被学生们接受。 此外，基金也 要求更换现有的单一接收器 四个新单位。 这项工作很重要，因为厄巴纳 雷达将有助于更好地了解纵向 平均风和潮汐的差异。

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.
