FIELD: seismic prospecting. SUBSTANCE: route of seismic prospecting is probed with sound wave to obtain picture of seismic section, part of reflected wave is registered by receivers. Discrete values of signals of seismic routes belonging to preset interval of quantization are recorded, row coordinates of its picture center of scattering are set. Signal is complexified, corrected by amplitude and diminished with account of scale coefficient. Spectrum of each realization is determined. After this matrix of spectra is formed and picture is reconstructed by backward two-dimensional Fourier transform with content of matrix of spectra. EFFECT: method is meant for plotting of picture of dynamic deep sections of the Earth. 3 dwg
