Optimization in Tri-Axial Degaussing System Design

Abstract:
Contemporary ships, made of ferromagnetic materials, under the influence of Earth’s magnetic field produce an underwater magnetic anomaly. This anomaly, often called the magnetic signature, compromises the stealth and safety of the ship and needs to be minimized. This paper presents an efficient methodology for the design of optimal tri-axial degaussing system and estimation of coil currents in ships to minimize the magnetic signature of the ship. Designing such a system is a complex optimization problem, we address this problem with high dimensional variable selection technique along with linear regression techniques.
