Description
Summary:We report results from meteor head-echo observations utilizing the tristatic EISCAT 930 MHz radar system located in northern Scandinavia. The 930 MHz tristatic configuration provides meteor absolute geocentric Doppler speeds as well as very precise radiant information for those meteors that are detected by the three receivers. An overview of the methodology and a summary of the results obtained so far as well as orbital calculations are presented. These observations prove EISCAT to be a crucial instrument for the study of extraterrestrial particles entering the earth's upper atmosphere, in particular at very high geocentric latitudes.
