When tri-axial magnetic sensor swaying with the moored-mine,the measured magnetic field's module will have a big error.So change o magnetic field caused by the ship may be submersed by the background noise.For solve thi problem,it constructs the measurement equation o ship's magnetic field on the base of moored-mine' swaying model.And the simulation result given by the MATLAB proved that it can detect the change of magnetic field's module from the difference between two Tri-axial Magnetic Sensors' measurement.
