Artificial Ionospheric Turbulence and Radio Wave Propagation (Sura - HAARP)

This report results from a contract tasking Radio Physical Research Institute NIRFI as follows The objectives of the project were i integrated experimental, theoretical and computer simulation studies of non-linear plasma phenomena, produced in the upper ionosphere by powerful HF radiation and giving rise to plasma density irregularities with a wide range of cross-field relatively to geomagnetic field lines scales from centimeters to tens of kilometers, ii investigation of an influence of these irregularities on characteristics of HF and VHF radio waves passed through the ionosphere disturbed volume, and iii control for long distance propagation of HF radio waves through an ionosphere wave-guide channel by means of radio wave scattering from small-scale field-aligned irregularities.
