Application of Sensitivity Vectors to the Measurement and Modelling of Magnetostatic Fields.

Abstract

The purpose of this report is to develop the analytic techniques required for quantitative assessment of the sensitivity of magnetic field measurements to quasi-static magnetic sources. To do this, we first use the concept of the gradient vector to define a 'sensitivity vector' for a given field measurement, and then relate this vector to the results obtained from the reciprocity theorem of electromagnetism. The derivations are then extended from magnetic dipoles to higher order moments. Several non-linear cases are examined, and techniques are developed to account for the presence of noise. (Author)
