| Abstract: | In the process of ultrasonic nondestructive testing, the flaw echo signals in A scan are correlative. Thus, it is possible to enhance flaw echo signals by means of adaptive filtering. The adaptive filter structure and LMS algorithm are described. From the results obtained in ultrasonic testing, it can be seen that the method has better performance and prospect. |
