概要

• 論文の詳細を見る

• A small artificial surface flaw on the surface of an aluminum thick plate was measured by SW-EMAT. The flaw echo was detected by a single burst pulse for the short distances and small LOs but it was impossible to detect it for a large distance(1000mm) and LO(0.6mm). It became clearly recognized after a combined digital signal processing of an averaging(8) and a mutual correlation.
