Abstract

본 발명은 라플라스 영역에서 파형 역산을 통해 지하구조를 모델링하는 영상화 기술에 관련된다. 본 발명에 따르면, 실제 송신원과 등가인 등가 송신원이 산출된다. 이 등가 송신원은 측정대상지역의 가상의 격자 상에 배열된 적어도 하나의 송신원이며, 이 가상의 격자는 실제 송신원의 위치로는 종래에는 채용이 불가능한 큰 크기를 갖는다. 이 등가 송신원 벡터는 실제 송신원(real souce)에 의한 반 무한 균질 매질(homogeneous half space)에서의 라플라스 영역 파동 방정식의 해석해(analytical solution)로부터 구한 해석해 벡터와, 라플라스 영역 파동 방정식의 임피던스 행렬을 곱하여 구해진다.
