The Extending of Observing Altitudes of Plasma and Ion Lines During Ionospheric Heating
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-26)
The ultrahigh-frequency observation during an ionospheric heating experiment on 11 March 2014 at the European Incoherent Scatter Scientific Association Tromsø site illustrated a remarkable extension of observing altitudes of the enhanced plasma line and the ion line, implying that the enhanced ion acoustic wave and Langmuir wave should satisfy the Bragg condition within the extending altitude range. ...
Systematic variation in observing altitude of enhanced ion line by the pump near fifth gyroharmonic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-20)
The observation of ultra high frequency radar during an ionospheric experiment carrying out at the European Incoherent Scatter Scientific Association, demonstrates a systematic variation in the altitude of the pump enhanced ion line, which is quite remarkably dependent on the pump frequency, that is, when the pump frequency sweeps above the fifth gyroharmonic, the altitude of the enhanced ion line ...
