Abstract
Statistical and algebraic techniques of subspace tracking were tested for filtering the earth’s
response from airborne magnetic field gradients in order to discriminate the relatively small
response (dipole) of objects on the earth’s surface, such as UXO. Filtering the data was not
very effective with these methods but a subspace was found in the data for the magnitude of
the magnetic moment of the dipole. This subspace is easily obtained using the singular value
decomposition and can be used for an approximate location, without depth estimation, as well
as the relative size of the dipole.
