A Novel Real-Time Aeromagnetic Compensation Method Based on RLSQ

Aeromagnetic compensation is important for aeromagnetic anomaly detection. This paper analyzes the time variation of Tolles-Lawson model widely used in aeromagnetic compensation. A novel real-time method based on recursive least squares is proposed and the simulation results illustrate this method has good ability to compensate the magnetic interference caused by the aircraft and its maneuvers.
