我们提出的人工电离层扰动的射线层析成像的结果，在最近的实验中得到的修改中纬度电离层的强大的HF无线电波在苏拉加热器进行。在专门安装的三个接收站网络上记录的PARUS低轨道信标卫星的无线电传输被用于加热电离层的遥感。我们讨论的可能性，以产生声重力波（AGW）与电离层加热的特殊制度（在几个小时内，在低于或相当于电离层高度中性大气的Brunt-Vaisala频率的频率上对有效辐射功率进行方波调制）并且呈现对应于加热器的方向性图案的电离层的受扰体积的空间结构的放射断层摄影图像，以及波浪状扰动的空间结构，这些扰动可能是加热引起的AGW，从电离层的加热区域发散。我们还研究了泵浦波通过苏拉加热器上方重建的扰动电离层的高频传播，显示了加热器产生的场对准不规则性的存在，这些不规则性有效地充当了“人工无线电窗口”。
We present the results of the radiotomographic imaging of the artificial ionospheric disturbances obtained in the recent experiments on the modification of the midlatitude ionosphere by powerful HF radiowaves carried out at the Sura heater. Radio transmissions from low orbital PARUS beacon satellites recorded at the specially installed network of three receiving sites were used for the remote sensing of the heated ionosphere. We discuss the possibility to generate acoustic‐gravity waves (AGWs) with special regimes of ionospheric heating (with the square wave modulation of the effective radiated power at the frequency lower than or of the order of the Brunt‐Vaisala frequency of the neutral atmosphere at ionospheric heights during several hours) and present radiotomographic images of the spatial structure of the disturbed volume of the ionosphere corresponding to the directivity pattern of the heater, as well as the spatial structure of the wave‐like disturbances, which are possibly heating‐induced AGWs, diverging from the heated area of the ionosphere. We also studied the HF propagation of the pumping wave through the reconstructed disturbed ionosphere above the Sura heater, showing the presence of heater‐created, field‐aligned irregularities that effectively serve as “artificial radio windows.”
