New Technique for Defect Indicator Fixing and Assessment at Rail Ultrasonic Inspection
Advanced methodology of flaw detector channels sensitivity setting for rail inspection is considered. The methodology also makes it possible to analyze and estimate amplitudes of signals that are lower than that of existing rejection level. The offered methodology realizes an adaptive threshold principle; characteristics of receivable signals that are measured by different statistics methods in every cycle of radiation-reception, are used as reference signals.
