Magnetic signature of submarine

Magnetic signature of submarine. Magnetic signatures of naval vessels. A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth's magnetic field. These disturbances can be used to trigger weapon systems.

  1. Magnetic signature of submarine

  2. Magnetic signatures of naval vessels • A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth's magnetic field. • These disturbances can be used to trigger weapon systems. • This can be avoided by demagnetizing the vessel by generating a counteracting magnetic field.

  3. Problem Definition Top: Vm=1989 (A) - corresponding to B0=0.5 (G) vessel parameters: length: 30 m diameter: 5 m hull thickness: 5 cm Sides: Bottom: Vm=0

  4. Weak form shell equation: -(mu0_nc*MUR*th*VmTx*VmTx_test+ mu0_nc*MUR*th*VmTy*VmTy_test+ mu0_nc*MUR*th*VmTz*VmTz_test)
