Analysis of Ultrasound Signal on Reflection from a Sharp Corner Surface: Study of Selected Characteristics Deriving from Regression by Transfer Function

This article deals with the regression analysis of ultrasonic signal amplitude when character reflection surface has been changed from a planar case to sharp corner case. The experiment was performed at measurement distance within interval 100 mm 215 mm. A nonlinear correlation between ultrasound and measured demonstrated. By analyzing frequency spectra, poor maximum component vector found for versus case, which proved similar characteristics as marker. strong linear in difference vectors confirmed hypothesis direct relationship geometric characteristic polarity difference. identified 3rd-order dynamic system. steady-state values modelled transfer functions likewise shows or derivative quantification marker point view.
