The paper reviews the characteristics of plasma-wave perturbations produced by wave-particle interactions in the magnetosphereionosphere system. These perturbations may, in particular, be due to lightning discharges and to the radiation of high-power, lowfrequency transmitters. These can form waveguide channels, i.e., density inhomogeneities, which originate in the ionosphere above the radiation source and extend along geomagnetic field lines in the magnetosphere. Аlthough different in nature, the natural and manmade radiations may have similar effects on the processes in the near-earth plasma, causing the excitation of a variety of emissions in it, and stimulating the precipitation of charged particles from the magnetosphere into the ionosphere.
