This paper addresses the detection and localization of a buried two-dimensional (2D) dielectric object in the presence of an air-Earth interface. The techniques used are modifications of the well-known backpropagation operator, including plane-wave a

Complex geological structures are modelled in the presence of an air-Earth interface. A cross-borehole configuration of target, source, and receiver is assumed, with the target itself not restricted as to geometrical cross section or complex permitti

Cross-borehole electromagnetic probing in the VHF band has been used successfully for locating underground tunnels and other subsurface structures, even when these are deeply buried and devoid of highcontrast reflecting materials. Full scale studies

The field scattered from a subsurface object illuminated by a transient pulse is determined using the T-matrix method. Although the method itself is a resonance-region, frequency-domain technique, it is shown that it can be applied to problems in whi

Scattering from subsurface objects is studied using the T-matrix method. The scatterer is represented by a dielectric ellipsoid, and the source is assumed to be an electric dipole in a borehole. This approach accommodates rotations of the scatterer r

A scale model developed for experimentally studying cross-borehole geophysical imaging is described. The model is about 1/40 scale and operates in the 2-3 GHz region. Earth in the form of sandy loam was used and reflections from the sides and bottom
