A linear approximation of the source position using multiple MAD

Abstract

Fcr certain assumptions, an analysis of multiple MAD signals results in a reasonable estimate for the localization of a target relative tc the MAD platform. This is achieved by using selective approximations to linearize an initially nonlinear problem. The simulation ignores noise and requires an estimate of the nagnitude of the target magnetic moment components. Results indicate that the best localization estimates are achieved when the platform is on cardinal headings, and when the -argst moment has a strong vertical component.
