Abstract
A method for ultrasonic guided wave defect detection in a structure is disclosed. The method includes driving a plurality of transducers to cause guided waves to be transmitted in the structure in a predetermined direction or focused at a predetermined focal point, receiving at least one reflected guided wave signal, and generating image data of the structure based on the at least one reflected guided wave signal. Processed image data are generated by performing at least one of baseline image subtraction or image suppression on the image data, and a location of at least one possible defect in the structure is identified based on the processed image data.
