A technique for studying inhomogeneous structure and motions in the ionosphere by measurements of wideband pulse radio signal amplitude and phase characteristics is developed and tested in investigations of the HF-pumped ionospheric volume above the Sura facility. For the vertical structure (electron density profile) reconstruction with high altitude and temporal resolution, an algorithm of inverse problem solving by using phase sounding data is implemented. Horizontal velocity data are obtained by means of correlation analysis of reflected signals received by diversity technique. Experimental results on electron density profile behavior and on reconstruction of 3D velocity field during HF pumping of the ionosphere are presented.
