Detecting Image of Void Shapes in Concrete Using Simulation Analysis Model of Reflection Wave of Electromagnetic Radar

전자파 레이더 모의해석에 의한 콘크리트 내부 공동형상별 화상검출 특성

More than effectively judging the existence of voids behind concrete tunnel linings or under concrete pavements, this research aims to develop the analysis algorithm of radar capable of estimation of the shape of specific voids. To detect or estimate void shapes in non-reinforced concrete, the simulation analysis model of transmission and reflection wave of electromagnetic radar is used. This radar simulation model is carried out with various void shapes. As the results, a proposed method in this study has a possibility of detecting or estimating void shapes with good accuracy.
