Abstract :
Detecting an underground object such as cable or plastic pipe in the Earth is important in geophysical and civil engineering. In this paper, a time-domain distorted Born iterative method is applied to a lossy half-space configuration to image a subsurface object from time-domain scattered fields measured at the surface, and measurement configurations to get a better image is investigated.
