Abstract
Dictionary matching techniques are an eective way to invert EMI measurements to detect properties of buried targets. A problem arises when trying to create a comprehensive dictionary that can account for location and orientation information for all types of useful targets because populating the dictionary would require the enumeration of parameters in a 7-dimensional space. This paper shows that the discrete spectrum of relaxation frequencies (DSRF) can be used to eliminate two of the dimensions entirely, and the singular value decomposition (SVD) will compress the dictionary by another two orders of magnitude. These dimensionality reducing techniques lead to an ecient dictionary matching algorithm for location and orientation estimates.
