Abstract:

This report presents a mathematical model of the steady magnetic anomaly produced by a submarine. it consists of several sub-models the earths magnetic field as a function of latitude, longitude and date models for the ferromagnetic moment of the submarine, including induced and permanent components, for both point and extended dipoles and a model for the magnetic field arising from steady galvanic corrosion currents. The model permits calculation of the magnetic anomaly, as it would be observed by an airborne magnetometer as a function of geographical location, submarine submerged displacement tonnage, speed, heading and depth, and aircraft altitude, course and speed.
