The　temporal-spatial　focusing　effect　of　the　Synthetic　Time-reversal　Focusing　Method　for　Guided　Wave　Pipe　Inspection　is　proved　through　both　simulation　and　experiment.　A　finite　element　model　of　a　steel　pipe　with　outer　diameter　of　114　mm　is　built.　And　a　crack-like　defect　is　made　on　the　pipe　model　to　be　focused　on　using　Synthetic　Time-reversal　Focusing　Method.　According　to　the　result　of　the　simulation,　the　reflected　echo　of　the　defect　is　greatly　enlarged　in　amplitude　and　improved　in　shape.　With　the　guidance　of　the　simulation,　an　experiment　is　carried　out　on　the　real　steel　pipe　with　outer　diameter　of　114mm.　The　experimental　result　is　similar　to　the　simulation.　So,　the　Synthetic　Time-reversal　Focusing　Method　is　proved　to　be　effective　in　Guided　wave　pipe　inspection.　©　2012　IEEE.
