Abstract :
A method using creeping wave for sizing a single cylindrical defect has been developed, which can relate the time of flight between the satellite pulse and the reflected pulse to the dimensions of a defect, and the three-dimensional defect reconstruction problem is simplified to a series of cross-sectional reconstructions.
