Abstract:
With recent advances in electromagnetic sensor technology, the war time threat to shipping posed by electromagnetically triggered mines is becoming more significant and consequently the need to understand, predict and reduce the electromagnetic signature of ships is growing. The detection threat arising from this induced magnetic signature has been known for many years, and consequently, ships are generally fitted with degaussing coils. The main aim of investigation of new methods for modeling magnetic signatures of marine vehicles due to their moving in earth'smagnetic field is the sophisticated procedure of modeling the details of structure and then meshing the model. So in this paper we will focus on a simple but practical model which fulfill our expectations. For our purpose, we are using the open source FEMM program. FEMM is a suite of programs for solving low frequency electromagnetic problems on two dimensional planar and axisymmetric domains. Whereas, our case is to magnetostatic problem
