“This little-known Pentagon-sponsored radiophysics project, called the High-Frequency Active Auroral Research Program (HAARP), is officially intended to expand knowledge about the nature of long-range radio communications and surveillance using the fluctuating ionosphere – the portion of the upper atmosphere extending from 35 to 500 miles above earth’s surface.
The IRI [ionospheric research instrument (HAARP)] is designed to temporarily modify 30-mile diameter patches of the upper atmosphere by exciting, or “heating,” their constituent electrons and ions with focused beams of powerful, highfrequency radio energy. A household analogy would be a microwave oven, which heats dinner by exciting the food’s water molecules with microwave energy.
Earth-penetrating tomography is a startling potential use of ionospheric heating. The method would work by beaming radio energy into the Auroral electrojet, the curved, charged-particle stream formed at high latitudes where the solar wind interacts with Earth’s magnetic field. The radio energy then disperses over large areas through ductlike regions of the ionosphere, forming a virtual antenna that can be thousands of miles in length. [CJF emphasis added]
Such an ELF antenna can emit waves penetrating as deeply as several kilometers into the ground, depending on the geological makeup and subsurface water conditions in a targeted area. Aircraft or satellites stationed overhead would then collect the reflected ELF waves and relay them to computers at a processing station, where subsurface inhomogeneities…can be imaged.”
