海洋环境工频磁场量级的快速估计方法

摘要

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.%海洋环境中工频电磁场是舰船水下电磁场测量的重要干扰源之一.对工频电磁场进行测量时由于水下布放难度较大,对测试海域进行多点测量并不现实.通过对工频电磁场海水中透射基本理论的分析,提出了一种工频磁场的快速估计方法,实测验证了方法的有效性.
