It is shown that the surface Rayleigh wave propagation at its responds to deepened and localized vertical and horizontal heterogeneity. In general, if the seismic velocities in the inhomogeneity higher than in the surrounding half-amplitude of the inhomogeneity of the vertical component is reduced if the speed nonuniformity is lower than in the surrounding half-amplitude of the vertical component increases. Developed algorithms and software control of the complex marine environmental hazards from the submerged and silted objects. Proposed and implemented the method of pre-processing of data obtained side-scan sonar. Proposed and implemented method of accounting distortions introduced by directional characteristic sonar across the span, the adjustment is carried out through a process of normalization, based on the average signal intensity for each slip angle. The method of correction of amplitude and geometric distortion sonar images Product Description popup.authors Гончар Анатолій Іванович Клочан Юрій Анатолійович Новіков Віктор Олександрович Шундель Олексій Іванович popup.nrat_date 2020-04-02 Close
