Abstract :
The nonlinearized reconstruction of geometry and electrical characteristics of homogeneous obstacles buried in a half-space is investigated. The sources and sensors are placed in the other homogeneous half-space. To solve this non linear and ill-posed problem, an adaptive scheme based on the use of B-spline basis is proposed. The proposed numerical results show the possibilities of this inversion scheme.
