Various Green’s functions occurring in Poisson potential field theory can be used to construct non-orthogonal, non-compact, continuous wavelets. Such a construction leads to relations between the horizontal derivatives of geophysical field measurements at all heights, and the wavelet transform of the zero height field. The resulting theory lends itself to a number of different applications in t...

S U M M A R Y Edge effects are distortions at the edge of a domain which are artifacts of the implicit assumptions of a numerical algorithm or of the limited span of data used to solve the problem (Sheriff, 1991, p. 96). During wavenumber domain filtering of potential-field data, (e.g., reduction to the pole, pseudogravity, and directional derivative, etc.), edge effect distortions are usually ...

Magnetic surveys have been widely used in archaeological field investigations. However, conventional survey methods are often restricted by complicated conditions and ambiguities data interpretation. In this study, a novel magnetic system was designed for pre-archaeological investigation (preliminary prior to the excavation) based on modified quadrotor unmanned aerial vehicle (UAV) successfully...
