摘要
介绍了一套海洋全张量磁梯度系统,专门用于测量地球磁场三分量数据及张量磁力梯度数据,并实时采集设备的定位信息及姿态信息,以便于后续数据处理。系统由两组三分量磁力仪、惯导设备、GPS定位设备、温度/压力传感器等组成,特别适用于测量地磁场矢量空间的磁场变化率,在磁法勘探中的解释效果明显优于单探头标量测量和三探头标量梯度测量。
A set of marine full tensor magnetic gradient system has been introduced.It is used to measure the earth＇ s magnetic field vector data and tensor magnetic gradient data.At the same time,it gives the equipment the real-time location information and the posture information for the subsequent data processing.This system is composed by two vector magnetometers,inertial navigation equipment,GPS device and temperature/pressure sensors.It is particularly suitable for measuring the rate of change of the vector magnetic field.The result is significantly better than the single probe measurement and the three probes scalar gradient measurement in the magnetic exploration.
