U.S.-France Cooperative Research: HF and VHF Radar Observations of Mid-Latitude Sporadic-E

这项为期两年的合同将支持美法在电动力学、等离子体不稳定性和高层大气中偶发e现象的雷达研究方面的合作研究。该项目涉及伊利诺伊大学厄巴纳-香槟分校的Erhan Kudeki和Steven Franke，雷恩一世大学的Alain Bourdillon和土伦大学的Christian Hanuise。调查人员建议建立一个由法国提供的便携式高频雷达系统，以补充波多黎各庞塞的三传感器甚高频雷达干涉仪系统。这两种雷达系统将为一项拟议的火箭实验提供全面的地面支持，以监测米尺度场对准等离子体不规则性的结构和动力学。使用甚高频和高频系统将允许比较公制和十米制尺度的不规则结构。该项目将促进对造成零星e不规则现象的不稳定过程的理解，并为火箭发射决策提供关键信息。

This two-year award provides support for US-France cooperative research on radar studies of electrodynamics and plasma instabilities and sporadic-E phenomenon in the upper atmosphere. The project involves Erhan Kudeki and Steven Franke at the University of Illinois, Urbana-Champaign, Alain Bourdillon of the University of Rennes I, and Christian Hanuise of the University of Toulon. The investigators propose to set up a portable HF radar system, provided by the French, to complement a three-sensor VHF radar interferometer system in Ponce, Puerto Rico. Both radar systems will provide comprehensive ground base support for a proposed rocket experiment to monitor the structure and dynamics of meter scale field-aligned plasma irregularities. Use of the VHF and HF systems will allow for comparisons of metric and decametric scale irregularity structure. The project will advance understanding of the instability processes responsible for sporadic-E irregularities and provide crucial information for rocket launch decisions.
