Abstract

Detectability of close reflection peaks in ultrasonic NDT system has been significantly enhanced by using a diverse field algorithm. The CLEAN algorithm, which is popular in image processing of radio astronomy data, has been proposed in the case of ultrasonic testing. The feasibility study of the algorithm has been performed successfully in the application of ultrasonic signal processing and it is conceived that the algorithm might have good potential in ultrasonic NDT for distinguishing between close peaks and removing sidelobes.
