本文介绍了高频增强离子声和Langmuir等离子体波参数的实验研究结果，以及小规模人工场对准不规则（AFAIs），当EISCAT/加热有效辐射功率从10到560 MW变化时。在实验过程中，以f2层截止频率以下的7.953 MHz频率向磁天顶发射了普通（o模式）和特殊（x模式）交替极化的高功率高频无线电波。在O型和x型高频泵浦下，人工离子声和Langmuir湍流的发展存在根本差异，在EISCAT光谱中表现为HF增强离子和等离子体谱线。利用0模和x模高频抽运的实验数据，确定了HF增强离子线和等离子体线以及小规模人工场排列不规则开始被激发时，电离层中HF抽运波电场的最小值。比较了在高纬度电离层f2层热、Langmuir和离子声模式下激发人工电离层湍流所需电场的实验阈值和理论阈值。
We present the results of experimental studies of the parameters of HF-enhanced ion–acoustic and Langmuir plasma waves, as well as small-scale artificial field-aligned irregularities (AFAIs) when the EISCAT/Heating effective radiated power is varied from 10 to 560 MW. In the course of the experiments, a high-power HF radio wave with the alternating ordinary (O-mode) and extraordinary (X-mode) polarizations was radiated towards the magnetic zenith at a frequency of 7.953 MHz lying below the cutoff frequency of the F2layer. A fundamental difference in the development of artificial ion–acoustic and Langmuir turbulence, which is seen as HF-enhanced ion and plasma lines in the EISCAT spectra, under the O- and X-mode HF pumping was found. The minimum values of the HF pump-wave electric fields in the ionosphere when the HF-enhanced ion and plasma lines, as well as small-scale artificial field-aligned irregularities, start to be excited, were determined from experimental data both for the O- and X-mode HF pumping. Comparison between the experimental and theoretical threshold values of the electric field required for the excitation of artificial ionospheric turbulence in thermal, Langmuir, and ion–acoustic modes in the high-latitude ionospheric F2layer for the O-mode HF pump wave was made.
