Strong field aligned scattering of UHF radio waves in ionospheric modification

The excitation of super-small-scale (SSS) field aligned plasma density disturbances in ionospheric modification by powerful radio waves is predicted. The SSS disturbances are generated when the frequency of pump radio wave is close to multiple gyroharmonic. The SSS inhomogeneities could to provide a basis for strong scattering of UHF radio waves with frequencies up to 1–3 GHz.
