Determining the location and orientation of a buried target. The method assumes the object is a point dipole and exploits an analytic relation between the field measured at r
i
and the scalar potential at the same point to find the location 
. The potential is constructed using a layer of equivalent magnetic sources placed between the sensor and the object; 
is a typical location on the layer.
