The Statistical Performance of the Matched Filter for Anomaly Detection Using Gravity Gradients
Jekeli, Christopher; Abt, Tin Lian (2010-05)
This document first reviews the theory of detecting a subsurface linear anomaly using the matched filter applied to observations of the gravitational gradient in the presence of a nominal gravitational background field ...
Detection of a Local Mass Anomaly in the Shallow Subsurface by Applying a Matched Filter
Abt, Tin Lian (2011-08)
The task is to locate a mass anomaly, particularly a void, in the near subsurface based on gravity, gravity gradients, and magnetic field data. The motivation for this search rises from multiple areas of applications ...
