摘要
本文根据试验观测结果,探讨了核旋仪探头高度改变对野外流动地磁场总强度观测质量的影响。认为适当提高探头高度,可以有效地消除地表物质不均匀磁性所带来的随机干扰。具体的探头高度可由不同工作区域的试验工作加以确定。
According to the results of experimental observation, the influence of the sensor height of proton procession magnetometers on the quality of the mobile total field measurement has been examined.
A higher location of the sensor can notably clean up the stochastic disturbance caused by heterogeneous magnetic materials on the ground. The appropriate sensor height may be decided by experiment in the survey site.
