Abstract
Narrow beam VHF radars are able to detect transient ionization at heights between 80 and 120 km produced by meteoroids entering the atmosphere 'down-the-beam'. Using a vertically directed beam, observations of this new type of meteor echo on two orthogonal receiving arrays enable the orientation of the plane of polarization to be measured. Significant Faraday rotation is observed to occur during daytime at heights above 80 km. Such observations make possible the measurement of ionospheric electron density profiles between heights of 80 and 120 km. © 1997 Elsevier Science Ltd.
