SPEAR是一个新的极地帽高频雷达设施，将部署在斯瓦尔巴群岛。SPEAR的主要能力将包括产生人造等离子体不规则现象，作为“全天候”高频雷达运行，激发超高频波，以及对磁层进行远程探测。SPEAR与斯瓦尔巴群岛上的许多其他仪器（包括EISCAT斯瓦尔巴群岛雷达）一起运行，并将其广泛的视野与SuperDARN网络中的几个高频雷达重叠，将能够深入诊断与尖峰区域和亚风暴扩展阶段相关的许多地球物理和等离子体现象。此外，它产生人造雷达极光的能力将为其他仪器在受控的情况下进行极帽等离子体物理实验提供手段。该设施的另一个潜在用途是“田间线标记”实验，用于协调地面卫星实验。这里详细介绍了SPEAR的科学目标，以及该系统的拟议技术规范。
SPEAR is a new polar cap HF radar facility which is to be deployed on Svalbard. The principal capabilities of SPEAR will include the generation of artificial plasma irregularities, operation as an ‘all-sky’ HF radar, the excitation of ULF waves, and remote sounding of the magnetosphere. Operation of SPEAR in conjunction with the multitude of other instruments on Svalbard, including the EISCAT Svalbard radar, and the overlap of its extensive field-of-view with that of several of the HF radars in the SuperDARN network, will enable in-depth diagnosis of many geophysical and plasma phenomena associated with the cusp region and the substorm expansion phase. Moreover, its ability to produce artificial radar aurora will provide a means for the other instruments to undertake polar cap plasma physics experiments in a controlled manner. Another potential use of the facility is in ‚field-line tagging’ experiments, for coordinated ground-satellite experiments. Here the scientific objectives of SPEAR are detailed, along with the proposed technical specifications of the system.
