Abstract : Nine articles devoted to the study of the properties of inhomogeneities in the ionosphere ranging in dimensions from tens of meters to hundreds of kilometers are presented. The development of the three-point correlation analysis method is discussed, whereby two-dimensional analysis is developed for a case of three measurements. A method is described and results are given of investigations from 1957-1959 on the properties of large ionospheric inhomogeneities within the space of three measurements by combining spacediversity and frequency-separation reception. The properties of small inhomogeneities are investigated using the correlation method, and the results obtained by the method of similarity and by the correlation method are compared. The movement of disturbances embracing extensive area of the ionosphere is given. The polarization of radio waves and its influence on the methods of observing ionospheric inhomogeneities is investigated. The use of the correlation method is considered in the study of the properties of ionospheric inhomogeneities. The results of the investigations of ionospheric drifts for new points (lrkutsk, Rostov), at which considerable material was collected during the IGY are given. (Author)
