Synthetic aperture array dipole moment detector and localizer

Abstract From the Canadian patent

A synthetic array comprising a moving magnetic sensor that provides a signal representative of an array of magnetic sensors is coupled to a digital signal processor is used to break a magnetic dipole field into its components and a magnetic, signature of, the present magnetic field is created. Predicted dipole signatures are precomputed for multiple magnetic orientations of the dipole at each of a plurality of range locations expressed in terms of Anderson functions which are a set of equations that decompose the magnetic field in each of the magnetic response locations and are stored in a lookup, table for reference. Input data measured by the moving synthetic array are processed and each …
