概要
This paper is concerned with signal processing arising in pipe wall thinning measurements using electromagnetic acoustic transducer (EMAT). First, electromagnetic acoustic resonance method (EMAR) is applied to pipe wall thickness measurement. Secondly, a heuristic method for extracting features of resonance spectrum obtained by testing data is proposed. Finally , the validity and the feasibility of our proposed method are demonstrated through the practical test at the real plant.
