Collection and Analysis of 3D Magnetic Data for UXO Discrimination

Abstract

Magnetic and electromagnetic responses are fundamentally three-dimensional phenomena that we visualize in two dimensions for simplicity. In a single 1D profile, measurement noise and interpretational ambiguities can be reduced at any given point by considering the values of neighboring points along the line. Similarly, noise levels and interpretations can be further enhanced by extending the process from 1D to 2D by considering the values of neighboring lines. It is reasonable to expect that a similar improvement can be obtained by extending this concept from 2D to 3D.
