The research carried out was aimed primarily at determining the electromagnetic environment of the earth for wavelengths between 20 meters and 6 kilometers. Measurements of the radio environment of the earth were conducted with rocket probes and near earth satellites at several discrete frequencies within this band. A considerable amount of theoretical research was also done in particular, the problems of the interaction of the electromagnetic radiation with the terrestrial ionosphere were studied, and theoretical models of the source of radiation in this wavelength interval were produced. This research is of prime interest to radio astronomy and astrophysics, ionospheric physics, and MF and HF communications.
