Experiments in ionospheric modification, i.e., the introduction of chemical or radioactive agents into the ionosphere for the purpose of altering electron concentrations and thus ionization levels, have been conducted by the USSR, the US, and Britain in order to develop methods of ensuring communications reliability of friendly forces and disrupting enemy communications in the event of war. Primary attention in this report is focused on Soviet interest in the single most important such experiment, namely, the study of the effects of a nuclear burst at a given height on radar and radio-wave propagation characteristics. Other non-nuclear, but germane, experiments as, for example, investigations of ray paths in artificially created ionized clouds, are also discussed.
