On Features of the Generation of Artificial Ionospheric Irregularities with Transverse Scales of 50–200 m

Abstract

We consider the features of generation of artificial ionospheric irregularities with transverse (to the geomagnetic field) scales l_⊥ ≈ 50–200 m in the ionosphere modified by high-power HF radio waves. It was found that there are at least two mechanisms for generation of these irregularities in the ionospheric F region. The first mechanism is related to the resonant interaction between radio waves and the ionospheric plasma, while the second one takes place even in the absence of the resonant interaction. Different polarization of the high-power radiation was used to separate the mechanisms in the measurements.
