In this paper a method for simulation of the magnetic signature of vessels is presented. This method includes
using a special magnet array - called Halbach magnet array - for produ cing a uniform magnetic field as a
source that models Earth’s magn etic field. Simplicity of this array beside its proper uniformity makes it possible
to perform simulation with acceptable precision. Fo r validating the proposed m ethod and determination of its
error, two simple models of spherical shell and prolate spheroidal shell that can be analytically handled are
used and a comparison has been done between simulation results of these models and their analytic signatures.
Good adaptability between these results confirms the accuracy of the proposed method and determines its
precision level. After being ensured that this method works well, two real ship models with the dimensions of 20
m and 130 m are used to perform realistic simulation and their magnetic signatures are presented in 10 m depth.
