| Abstract: | We present measured characteristics of the artificial ionospheric radio emission (AIRE), which were obtained experimentally
using additional heating of the ionospheric F-region by O-polarized waves. It is shown that the observed enhancement of intensity
of the broad upshifted maximum (BUM) of the AIRE can result from the influence of electrons accelerated in the plasma: esonance
region on its generation. An empirical model of the phenomenon observed is developed. It is concluded from experimental results
that the BUM has a complex structure and only one of its components produces the above emission enhancement. We show the possibility
of using the AIRE in additional heating of ionospheric plasma for diagnostics of artificial ionospheric turbulence and investigation
of the features of perturbation propagation along the geomagnetic field lines.
