A Method for Determining the Electron Density Profile in the D-Region of the Ionosphere

摘要

On the basis of results measuring non-deviative absorption L sub D in the D-region with moderately high frequencies, the distribution law for electron density can be determined as a function of altitude. In order to do this, we solve an integral equation for absorption using an analytical method of successive expansion by a Taylor's series. Thus, by using the recorded L sub D during oblique incidence of an electromagnetic wave on a series of points, or by measuring absorption at several frequencies in the Al region, the form of N(z) in the D-region can be determined by simple methods, and its periodic variation can be controlled.
