Phased array ultrasonic S-scan testing of near-detection-surface defects based on a background subtraction algorithm
In phased array ultrasonic sector scanning testing, echoes from defects near the detection surface are often overlapped with interface echoes and cannot be characterized. Based on linear acoustic theory, a mathematical model combining the background subtraction and the sum of squares differences alg...
