Numerical Simulation of the Distribution of the Low-Frequency Field Created by a Transmitting Loop Antenna Installed on Board a Spacecraft

Abstract

Based on the results of numerical calculations of the intensity of the low-frequency (LF) electric field of an emitter in the form of a loop antenna installed on board an artificial Earth satellite, this quantity was compared with the strength of the field demodulated in the lower ionosphere, perturbed by the radiation of a high-power high-frequency (HF) transmitter (HAARP station, Alaska). It is shown that the onboard low-frequency transmitter with a power of ~1 kW is able in the lower ionosphere to provide approximately the same field strength as the HAARP demodulator with an average power consumption of the HF transmitter of 3.6 MW.
