FHD VECTOR PROTON MAGNETOMETER CALIBRATION TECHNOLOGY

  • 摘要: FHD分量质子磁力仪利用补偿测量方法(Nelson方法)测量水平分量,利用偏置测量方法(Sensor方法)测量磁偏角的相对变化,由于装置存在误差和长期漂移,会对观测数据的长期稳定性产生影响,为了消除或校正这些影响,对观测误差进行分析,提出对相关影响因素进行校正的方法和步骤,并提出观测系统漂移量的判断和估算方法,以及在标定过程中应注意的问题,对FHD质子磁力仪的标定效果和质量起到较好的监控作用。

     

    Abstract: FHD vector proton magnetometer use compensation measuring method(Nelson method) and a bias measuring method(Sensor method) for measuring horizontal vector and magnetic declination relative changes.However, instrumental error and long-term drift will have effects on the long-term stability of observation data.In order to eliminate or correct the effect, this paper analyzes the observation error and puts forward a correlative factors correction method and steps, and also puts forward the forward observation system drift amount judgment and estimation methods, as well as the problems in the calibration process that should be paid attention to.These measures have a great monitoring effect on the FHD proton magnetometer calibration effect and quality.
