Radiophysical Investigations and Modeling of Ionospheric Processes Generated by Sources of Various Nature. 2. Processes in a Modified Ionosphere. Signal Parameter Variations. Disturbance Simulation

Abstract

The paper presents results of observations of the variety of processes triggered by rocket launches, flights and descents of space vehicles, chemical or nuclear explosions, impact of powerful radio waves of the decameter and hectometer wavebands, and injections of plasma extinguishing or plasma producing chemicals. The physical mechanisms responsible for transport of the plasma disturbances are discussed. Variations in the parameters of radio signals and noise at frequencies between 1 kHz and 4 GHz are investigated, and models of the disturbances described.
