ANALYSIS OF MODEL ACCURACY AND MAGNETIC SIGNATURE OF A SHIP SCALE MODEL

摘要

The paper describes the analysis of a naval ship permanent magnetization by employing a physical scale model. The experimental setup consists in a shielded room of non-ferromagnetic materials surrounded by a triaxial Helmholtz coil system, an automatic compensation system, and a mobile platform moving horizontally. There were performed several triaxial measurements of magnetic signature, in horizontal planes below the model hull. The paper illustrates the model magnetic field at normal measurement depth. Part of the obtained results were compared to a set of measurements of vertical magnetic signature on the original ship.
