Calculation of Ionospheric Profiles by Inverting VLF/LF Reflection Data. II. Anisotropic Propagation.

Abstract

This report describes a method for inverting VLF/LF reflection data to obtain ionospheric electron densities for conditions in which the geomagnetic field causes the propagation to be anisotropic. It extends an earlier inversion method that was useful only for conditions in which the propagation could be assumed isotropic. The anisotropic method is demonstrated by inverting computer-generated reflection and conversion coefficients for three model ionospheres: SPE-disturbed, ambient daytime, and ambient nighttime. Satisfactory results were obtained for all three cases. Originator-supplied key words include: Ionosounding, VLF/LF reflection, VLF/LF inverse problems, and Lower ionosphere.
