A Versatile Electromagnetic Waveform Receiver for South Pole Station

地球极光在低、中、高频发射出范围广泛、种类繁多的无线电波，这是极光电子束与电离层等离子体相互作用的标志。这种相互作用及其结果，例如等离子体波的产生机制，目前还不是很清楚。该项目将在南极站部署一个多功能的电磁波形式接收器，并专注于几种在地面上可以检测到的信号。南极的位置对这项研究至关重要，因为在北半球，低频段和中频段被广播频段遮挡住了。干净的南极光谱提高了自动波浪检测算法的效率，这是数据管理协议的必要部分。该接收器将构成位于美国运营的自动地球物理观测站的接收器网络的一部分。南极计划和英国南极调查，从而覆盖了大范围的地磁纬度。

The Earth's aurora emits a wide range and variety of radio waves at low, medium, and high frequencies, which are signatures of the interaction between the auroral electron beam and the ionospheric plasma. Such interactions and their results, for example plasma wave generation mechanisms, are currently not well understood. This project will deploy a versatile electromagnetic wave form receiver at South Pole station, and focus on several types of signals detectable at ground level. An Antarctic location is essential for this study because in the Northern Hemisphere the low and medium frequency spectrum is obscured by broadcast bands. The clean Antarctic spectrum improves the effectiveness of automatic wave detection algorithms which are a necessary part of the data management protocol. This receiver will form part of a network of receivers located in the Automatic Geophysical Observatories operated by the US. Antarctic program and by the British Antarctic Survey, thus providing coverage at a wide range of geomagnetic latitudes.
