A review is given of the current state-of-the-art of experimental studies and theoretical understanding of nonlinear phenomena that occur in the F-region ionosphere irradiated by high-power high-frequency ground-based transmitters. The main focus is on the dynamic features of high-frequency turbulence (plasma waves) and low-frequency turbulence (density inhomogeneities of various scales) that have been studied at the SURA and HAARP heating facilities operated in temporal and frequency regimes specially designed with consideration of the characteristic properties of nonlinear processes in the perturbed ionosphere using modern radio receivers and optical instruments. Experimental results are compared with theoretical turbulence models for a magnetized collisional plasma in a high-power electromagnetic field, allowing the identification of the processes responsible for the observed features of artificial ionospheric turbulence.
