On the use of complex attributes and the inferred source parameter estimates in the exploration of archaeological sites
G. N. Tsokas, R. O. Hansen · Archaeological Prospection · 2000
Complex attribute analysis is used to extract parameters of the buried structures that give rise to anomalous total magnetic field. The attributes by themselves aid the interpretation because they can delineate the edges of the concealed targets. Tests on synthetic and real data demonstrate this property. Parameters such as the local depth, dip, dip azimuth, strike and susceptibility contrast are obtained from the complex attributes on the basis of an analytical expression for the effect of a simple subsurface model. The simplest one, the sloping contact model, is used in this study. The local parameters of the concealed targets aid the interpretation further. They can also be used alone to interpret the anomalous field. Interference of the signals caused by nearby buried structures and the noise level limit the extent to which the source parameter estimates can be used. Copyright © 2000 John Wiley & Sons, Ltd.
