摘 要: | Ultrasonic phased array technology has been gradually applied to industrial nondestructive testing in recent years. The sound field of the focusing and steering beam radiating from the phased array is a nonuniform distribution in the spatial position so that the echo signals of same size defects will be changed according to defect positions. To analyze these defects quantitatively, a model-based method for the distance amplitude correction is proposed for the phased array system. Based on a non-...
