Study of Equatorial Ionospheric irregularities and Mapping of Electron Density Profiles and Ionograms

Abstract

This report covers study of plasma bubbles through their spread echo in ionograms limiting to equatorial ionosphere, for the reasons: (1)part of the Philippines lies at the magnetic equator, (2) equatorial ionosphere is not well understood, (3) plasma bubbles form in the equatorial ionosphere, and (4) the equations are simpler because the magnetic field is nearly horizontal, so that the ionospheric layers are also nearly horizontal. Also study plasma bubbles to determine from an ionogram, the electron density as a function of true height which is not a very easy problem. Generate the ionogram as a plot of the virtual height of the ionosphere as a function of the carrier frequency of the radio wave. This study shall generate an atlas of all possible electron density profiles and derive the ionograms. Using experimentally obtained ionograms and comparing with the theoretical ionograms, the corresponding electron density profile of the ionogram shall be found.
