Radar Observations of Meteor Created Plasma Interactions in the Atmosphere

High Power Large Aperture (HPLA) radars have been used to monitor meteor head echoes for more than decade now. The method developed at the EISCAT Incoherent Scatter Facility in Northern Europe will be reviewed. This includes a general discussion of what parameters can be derived from the information sampled from head and trail echo observations. Various kinds of measurement strategies, such as multi-frequency, multi-static, pulse codes, geographic effects, perpendicular to magnetic field observations and observations along the Earth orbit are described. These will be related to what kind of information could be delivered to dust plasma interaction community.
