Demagnetization and signature measurement system

A device (2) for demagnetizing and for measuring the magnetic signature of a stationary hull (4) and for simulating a magnetic field (20a, 20b, 20c), comprising a demagnetization coil assembly (8), a magnetic field sensor assembly (10) and a simulation coil assembly (12a, 12b, 12c),

• wherein
• the device (2) can be positioned horizontally next to the hull (4) on one side in the longitudinal direction of the hull (4),
• the demagnetization coil assembly (8) having a single demagnetization coil (8), the cross-sectional area of said demagnetization coil extending at least across the entire length of the hull (4) and the surface normal of said demagnetization coil being oriented orthogonally to the longitudinal direction of the hull (4), a stationary alternating magnetic field thus being producible outside the demagnetization coil (8), or the demagnetization coil assembly having at least two demagnetization coils (8), the cross-sectional areas of said demagnetization coils being disposed next to one another in the longitudinal direction of the hull (4) and the surface normals of said demagnetization coils being oriented orthogonally to the longitudinal direction of the hull (4), an alternating magnetic field (30a, 30b) progressing in the longitudinal direction of the hull (4) thus being producible outside the demagnetization coils (8).
