Abstract:

A simple presentation of ionospheric characteristics, including the D-, E-, and F-regions, is followed by a general description of electromagnetic waves. One of the more important effects of ionospheric interactions with the Very High Frequency VHF and Ultra High Frequency UHF radio waves, which are used in modern electronic detection and tracking systems, is refraction. Total electron content TEC measurements over specific locations are used as data inputs to numerical models of the ionosphere. Some of the basic considerations for measuring TEC of the ionosphere using the Faraday technique and the group- path-delay technique, and a discussion of variation of TEC are Included.
