Generation of radiation at combination frequencies in the region of the auroral electric jet

An experiment was performed aimed at recording radiation at combination frequencies when the ionosphere is acted upon, by high-power amplitude-modulated short-wave radio emission in the region of the auroral electric jet. It is found that the intensity of the radiation at the combination frequency depends on the distance between the auroral current jet from the center of the zone of the active action in the ionosphere, as well as on the strength of the current in the electric jet.
