摘要： 提出了一种新的深海海底三分量磁力仪设计思路，用于高灵敏度地磁测量调查海底矿体分布，其磁力测量探头基于各向异性磁阻传感器。详细分析了磁阻传感器的误差模型，提出用Broyden算法实现误差校正，并给出了在个人电脑上的实现结果。描述了水下系统中传感测量电路以及通信、存储功能的基本设计思路。最后给出目前的实验与测试数据，并提出了后续工作思路。

关键词: 误差校正, 误差校正, 长距离传输, 长距离传输

Abstract: A new design of 3-component magnetometer for deep ocean near seafloor is proposed to measure the geomagnetic field in high sensitivity for seafloor orebody investigation, whose magnetic field detector is based on Anisotropic Magneto Resistive (AMR) sensor. The error model of the sensor is analyzed in detail and the flow of correction procedure is given. The basic design of the sensor circuit, communication part and memory part is also discussed. Finally the experimental and test data to date is given, and the thinking of future work is discussed.

Key words: AMR sensor, AMR sensor, error compensation, error compensation, long-distance communication, long-distance communication
