Abstract :
The extended-Born technique is an approximate nonlinear method for analyzing scattering from a weak discontinuity. Moreover, when applied to the low-frequency (electromagnetic induction) applications for which it was developed originally, the extended-Born method has accurately modeled scattering from inhomogeneities considerably larger than those appropriate for the standard linear Born technique. We examine the extended-Born technique at radar frequencies considering three-dimensional (3-D) scattering from a dielectric target buried in a lossy half space
