A magnetic anomaly homing system uses an array of magnetic sensors coupled to
a
non-magnetic platform. The array is defined by a plurality of single-axis subsystems
with each one thereof having two magnetic sensors spaced apart from one another.
A processor coupled to the magnetic sensors generates a plurality of magnetic total
field scalars that can be used to directly home in on a magnetic object from both
long and short-range distances to the target. The scalars define guidance control
parameters used to steer the platform to align the platforms's direction of motion
with the magnetic anomaly.
