High-order inversion formulas for low-frequency imaging of 2D buried targets

Low frequency imaging of 2D buried targets by high-order inversion formulas was discussed. The use of inverse scattering of buried objects on the earth was important for geophysical probing and detection of landmines and unexploded ordnance (UXO). Born approximation was widely used for weak scatterers. It was observed that better image qualities could be attained using quasi-linear algorithms.link_to_subscribed_fulltex
