Multi station- and interferometric radar meteor head echo observations

We present highlights from meteor head echo observations with the tristatic EISCAT radar system in the Fenno-Scandinavian arctic region and the interferometric middle and upper atmosphere (MU) radar in Japan. The results are used in the context of providing an outlook for future multi station- and interferometric meteor observations with EISCAT_3D, a three-dimensional imaging radar project for atmospheric- and geospace research. EISCAT_3D will consist of multiple phased arrays located in northern Fenno-Scandinavia. It will offer extended possibilities to investigate the fine details of meteoroid-atmosphere interaction processes, as well as significantly increased accuracy of meteoroid orbit determination compared to currently available radar facilities world-wide.
