Web1 okt. 1990 · For these experiments we are introducing a new ET probe system, a low power oblique sounder, to be used along the same propagation path as the high power disturbing transmitter. This concept was first used by soviet researchers to insure that this diagnostic signal always passes through the modified region of the ionosphere. WebDefinition. The lower part of the Thermosphere; a layer of ionised air extending from the Mesopause to approximately 600km above the surface. Description. The ionosphere contains a high proportion of free electrons which influence radio propagation. High Frequency (HF) radio waves hitting the free electrons in the ionosphere cause them to …

Some results obtained in a radio propagation experiment involving the recording of the pattern of pulse signals received at a rocket from a ground-based transmitter are described. The technique readily permits the group retardation of the radio signal at different levels in the ionosphere to be measured and the level of reflection ...
Web2 mrt. 2024 · HAARP analyzes physics phenomena in the uppermost part of the atmosphere (known as the ionosphere) by studying the small heating effects the transmitter creates there that last for only a few seconds. Thus, it cannot affect human thought processes or movements in any way.
