| Abstract: | In ultrasonic guided wave pipe detection,different pipe features have different signal characteristics.In order to identify the features of a pipe automatically,a new method based on correlation is used to classify signals of different pipe features.In this method,the correlation of a unclassified signal and a standard signal is considered as the similarity of the two signals.So,by calculating the correlation of the unclassified signal and different types of standard signals,the unclassified signal can be c... |
