Research on modeling simulation and stability of underwater magnetic field for underwater target detection

In this paper, the mixed model of ellipsoid and Dipole of the target magnetic field in water is established by mathematical method, and the equivalent source of the target magnetic field is obtained based on the measured magnetic field data, finally, the magnetic field distribution at different depths is analyzed, and the very obvious magnetic field characteristics are obtained, it can be used as an important basis for underwater target detection. In this paper, the virtual-real correlation from solid object to digital magnetic field model is realized by magnetic field modeling, which provides rich data information and research perspective for the study of underwater target magnetic field.
