| Abstract(in English) | The inverse scattering problem to estimate the refractive index distributions of buried cylindrical objects is considered. The diffraction tomographic technique with transmitting and receiving antennas on the Earth's surface as well as two boreholes is used to image the objects. To solve the nonlinear integral equation for the unknown refractive index distribution, we define the functional as the norm of difference between the measured scattered field and the calculated one for an estimated index distribution. The functional is minimized by the conjugate gradient method. Numerical example shows that the resolution in the horizontal direction is improved by locating the receiving antennas on the Earth's surface. |
