Inna B. Improvement of method and mean of ultrasonic products of thickness of materials with significant attenuation

The object of research is the process of determining the thickness made of materials with a significant attenuation of the ultrasonic pulse-echo method. The subject of this study is the method of statistical phase ultrasonic thickness made of materials with a significant attenuation of ultrasonic vibrations on the basis of analysis of the phase characteristics of the signals. First proposed method of phase ultrasonic thickness based on a statistical analysis of the phase characteristics of the signals. Justified the use of time windows for signal processing ultrasonic thickness. First proposed a new information sign for ultrasonic thickness - spot the resulting length of the vector. First suggested to choose the decision threshold of a echo and assess the likelihood of their identification by the analysis of a sample of the resultant vector length. First proposed to estimate the signal /noise ratio at the output of the phase detector signals for non-energy ultrasonic thickness characterization.
