Baseline-Free Damage Imaging Algorithm Using Spatial Frequency Domain Virtual Time Reversal

Structural health monitoring (SHM) techniques are widely used in industry applications to guarantee the integrity of several types of components. Ultrasonic guided wave (GW) methods for damage imaging typically use baseline signals from the undamaged component, which are often affected by real opera...
