A 2.5-D diffraction tomography inversion scheme for ground penetrating radar

A new 2.5-D inversion scheme is derived for ground penetrating radar (GPR) that applies to a monostatic fixed-offset measurement configuration. The inversion scheme, which is based upon the first Born approximation and the pseudo-inverse operator, takes rigorously into account the planar air-soil interface, the loss in the soil, and the characteristics of the antennas.
