航磁测量飞机飞行姿态影响及矫正

摘要

In order to eliminate the magnetic interference such as induced magnetic field, eddy magnetic field produced by the change of aircraft attitude in aeromagnetic survey, the interference field model is presented in this paper.We use the method of compensation to correct the affection of the aircraft attitude.To verify the validity of the method, we process the aeromagnetic data of M area by correcting the real-time posture.The results show that after correction the magnetic data of total field are in accordance with the International Geomagnetic Reference Field.In conclusion, the real time compensation method can eliminate the effect of the aircraft on the quality of the magnetic survey.%为消除航磁测量过程中由于飞机姿态变化而产生的感应磁场、涡流磁场等磁干扰，本文建立了干扰场模型，用补偿的方法对飞机飞行姿态产生的影响进行矫正。为验证方法的有效性，对 M 区实测航磁数据进行实时姿态矫正处理，结果显示，处理后的磁总场数据与国际标准地磁场基本吻合。证明本文提出的实时补偿方法能够消除飞机飞行姿态对磁测质量的影响。
