The Ivory Coral Program on Ionospheric Modification

Abstract

The Ivory Coral program is an outgrowth of early ARPA over-the- horizon radar research. The primary objectives of the Ivory Coral program were to modify the ionosphere in a controllable manner, to determine the characteristics of the modified volume, and to develop and verify models of the modified volume. The results of the Ivory Coral program clearly demonstrate that the ionosphere can be modified and characterized when illuminated with reasonable RF power densities. Changes in the ionospheric electron density, electron temperature, and collision frequency have been observed and are reasonably well understood. Structuring of the modified volume has been observed using a variety of radio scattering and scintillation methods.
