Abstract

In the present work, the Synthetic Transmit Aperture (STA) imaging is applied on coarse grained steels using a contact phased-array probe. In order to reduce the noise introduced by the heterogeneous structure, as well as artifacts due to surface guided waves, the Decomposition of the Time Reversal Operator method is performed before calculating STA images.
