Monitoring of the Medium Stratification by the Parameters of the Surface Wave Field

A method for the low-frequencyLow-frequency monitoring non-destructive monitoring of medium stratificationMedium stratification according to the parameters of control of surfaceSurface wavesWave is proposed. The method consists in the control of the change of the characteristics of the surface wave fieldSurface wave field accompanying the change in the parameters of the stratification, and the corresponding transformation of the registered signal via original mathematical methods into a two-dimensional feature. This approach makes it possible to obtain visual observation of signal changes by transforming the initial value of the amplitude-time signal into the point in two-dimensional feature space. Deviating of the parameters of the waveWave field leads to changes to the point location in two-dimensional feature space. Thus, there is a possibility of visual observation of stratification parameters due to point location in two-dimensional feature space.
