We consider the results of the experiment on the polar ionosphere heating by a high-power modulated HF wave conducted by the AARI at the EISCAT/heating facility in October 2016. The data on joint processing of the values of the equivalent polar electrojet current above the heated ionosphere region retrieved by the IMAGE network of ground-based stations and the amplitudes of a signal of the horizontal component of the magnetic field from an ionospheric source at the modulation frequency recorded in the PGI network of high-latitude stations are presented. The events with a strong positive correlation between the magnetic field amplitude variations and the polar electrojet current variations are considered. It is shown that if the direction of the current changes from eastward to northward, correlation between the current variations and magnetic field variations almost disappears at a modulation frequency of 3017 Hz. Temporal and spatial variations of the coefficient of linear regression of the amplitude of the horizontal magnetic-field component with respect to the electrojet current are analyzed. In the transition from day to night, which is accompanied by the electrojet current decrease, the regression slope increases, and it decreases with increasing distance between the heater and the observation point.

调制电离层加热实验中极地电射流动力学与电离层源极低频/甚低频信号幅度的关系

我们考虑了 2016 年 10 月由 AARI 在 EISCAT/加热设施进行的高功率调制 HF 波对极地电离层加热的实验结果。显示了由地面站的 IMAGE 网络检索到的加热电离层区域，以及在高纬度站的 PGI 网络中记录的调制频率下来自电离层源的磁场水平分量信号的幅度。考虑了在磁场幅度变化和极性电喷射电流变化之间具有强正相关的事件。表明如果水流方向从东向北变化，电流变化和磁场变化之间的相关性在 3017 Hz 的调制频率下几乎消失。分析了水平磁场分量幅度相对于电喷射电流的线性回归系数的时间和空间变化。在从白天到黑夜的过渡过程中，伴随着电射流电流的减小，回归斜率增大，并且随着加热器与观测点距离的增加而减小。
