Whistlers as possible indicators of active effects on the ionosphere

As the result of experimental observations on the Kamchatka peninsula, a non-standard form of whistlers (whistling atmospherics) was detected. It is determined by amplitude modulation by an external electromagnetic pulse, lasting for about 1 second having the filling frequency of 1.1 kHz. The authors made a hypothesis about the possibility of using whistlers as an indicator of active impacts on the ionosphere. Thus, information about the parameters of artificial heating of the ionosphere can be reconstructed from whistler envelope, while the frequency dispersion contains data on electron concentration evolution.
