“…In the work of Bolotin et al. (2017), ionosonde signals were used for aspect scattering from irregularities of 50–200 m, and it was supposed that these irregularities appear most likely as the nonlinear cascade over the turbulence spectrum (Erukhimov et al., 1987).…”

“…The "magnetic zenith" effect and nonlinear plasma structuring as a result of self-focusing of the pump wave into plasma regions filled with small-scale artificial ionospheric irregularities elongated along the geomagnetic field leads to an increase in the generation of irregularities with scales from hundred meters to a kilometer (Frolov, 2017;Gurevich, 2007). In the work of Bolotin et al (2017), ionosonde signals were used for aspect scattering from irregularities of 50-200 m, and it was supposed that these irregularities appear most likely as the nonlinear cascade over the turbulence spectrum (Erukhimov et al, 1987).…”

This work presents the first results of measurements of artificial plasma disturbance characteristics using the low‐orbit NorSat‐1 satellite, which are excited when the ionospheric F2 layer is modified by powerful high‐frequency (HF) waves emitted by the SURA heating facility. NorSat‐1 carries the multineedle Langmuir probe instrument, which is capable of sampling the electron density at a nominal rate up to 1 kHz. The uniqueness of this experiment lies in the fact that the satellite passes very close to the center of the HF‐perturbed magnetic flux tube and in situ observations are first carried out in winter when the absorption is still small in the morning as the Sun is low above the horizon. There are HF‐induced plasma temperature and density variations at satellite altitudes of about 580 km. Plasma irregularities are detected by in situ measurements down to 200 m at the southern border of the SURA heating region.

“…We cannot but propose a mechanism for the interaction of a powerful radio wave with plasma, where under such ionospheric conditions, it would lead to the generation of intense artificial ionospheric irregularities. The observed phenomenon is connected with the presence of strong natural F spread (with strong natural irregularities with l ⊥ from 100 m to several kilometers) when the irregularities with l ⊥ ≈ 300–800 m are enhanced by powerful radio waves due to its self‐focusing instability, and at the second stage, these irregularities due to their nonlinear transformation give rise to irregularities with l ⊥ ≈ 100–200 m (Bolotin et al, 2017). In this case, strong scattering of radio waves in the ionosphere HF‐disturbed volume takes place as proposed by Zabotin et al (2002) together with F spread generation as it was observed in our experiments.…”

A total of 17 SURA‐China Seismo‐Electromagnetic Satellite (CSES) experiments in 2018 have been summarized and analyzed in multiple parameters detected in the topside ionosphere at altitude of 507 km from CSES. Most of them were fulfilled with underdense heating condition, and no any artificial density duct had been detected onboard CSES, but some plasma perturbations were actually observed in lower and topside ionosphere. Among them, different modulated waves were also transmitted by [power on, power off] and amplitude modulation modes on the pumping high‐frequency (HF) wave from SURA, and some were illustrated in HF electric field from CSES in local nighttime, one being verified at fmod in single component of very low frequency (VLF) electric field in local daytime. In addition, X mode‐emitted HF waves excited a filamentary structure on the existing VLF transmitters in local daytime, being different with those in O‐mode HF waves to enhance the VLF transmitter signals and widen their frequency band in local nighttime. These phenomena and their coupling process were discussed finally on the interaction of radio waves with plasma parameters in ionosphere.
