| Abstract: |
Objectives For the precision measurement of a ship's induced vertical magnetic signatures, a new method combining numerical analysis and geomagnetic simulating coils is proposed. Methods After the currents in the geomagnetic simulating coils are calibrated by numerical analysis, the coils are used to measure the ship's induced vertical magnetic fields.
A simulation experiment installation is established and an evaluation test performed on a magnetic ship mockup. Results The results indicate that the difference between the measurement values and standard values of the ship mockup's induced vertical magnetic fields falls within 4%, Conclusions which validates the theory that this technique can be used for the precision measurement of a ship's induced vertical magnetic fields with high practical value.
