| Abstract: |
| The power frequency electromagnetic component is a significant disturbance when we take measurement to the ship underwater electromagnetic field in ocean. During the measurement we found it′ s difficult to place the equipment underwater, so it′ s unpractical to measure the electromagnetic component at arbitrary position in the sea. By analyzing its theory of transmission, this paper presents a rapid estimation method of power frequency magnetic field, and validates its validity by experimentation. |
