Direction Finding of Magnetospheric VLF/ELF Emissions and Their Generation Mechanism

  • Chapter
Environmental and Space Electromagnetics

Abstract

The purpose of this report is to review our recent studies on the generation and propagation mechanisms of magnetospheric VLF/ELF emissions based on the direction finding measurements on board spacecrafts in order to demonstrate the potential use of the direction finding measurements in plasma wave studies. The plasma waves treated in this report are, (1) half-gyrofrequency VLF emissions, (2) ELF hiss in detached plasma regions of the magnetosphere, (3) plasmaspheric ELF hiss, and (4) VLF/ELF chorus. We then point out the technical problems to be investigated concerning the spacecraft direction finding measurement to be used for the future satellite experiments.
