Abstract
Mechanisms of generation and dynamics of HF and LF emissions related to an electron beam injection from a spacecraft into the ionosphere are studied. The choice of the source and region of emission is substantiated. The plasma current neutralizing the spacecraft charge and the region of spatial charge in the vicinity of the spacecraft are chosen. Mechanisms of the generation of HF and LF emissions are proposed and their characteristics are determined. For the considered ranges of emission, the explanation of the facts related to the difficulties in interpretation of the amplitude value observed experimentally and the behavior of its envelope are presented. It is shown that the results obtained in this work agree well with the data of the conducted experiments.
