Abstract

Numerical simulation of propagation of a demodulated beam of low-frequency electromagnetic waves at low latitudes in the presence of latitudinal gradients of the equatorial anomaly has been performed under the condition that the signal is recorded in the vertical direction, for example, with the use of sounding rockets. It has been shown that the wave beam has small spatial dimensions and, therefore, the amplitude distribution of the electromagnetic field in this beam is nonuniform owing to the interference effects under competitive action of the plasma density gradients and plasma anisotropy in the presence of a nonuniform geomagnetic field. Under these measurement conditions, the measurements usually conducted with the use of the instruments carried by an Earth satellite may become insufficient.
