Abstract
A method and system for compensating maneuver induced components in the magnetic field sensed by an airborne magnetic detector. The magnetic fields sensed during a series of selected aircraft maneuvers are processed to yield signals representative of the magnetic properties of the aircraft. Subsequently, these signals are combined with signals representative of the aircraft attitude to provide a compensation signal. This compensation signal may be applied directly to the output of the magnetic detector or may be used to drive a set of compensation coils.
