摘要 

超导航磁梯度张量数据补偿时,补偿模型的仿真结果与实际测量数据补偿结果往往存在一定差异。本文从实测数据出发,以建立对实测数据有效的模型为目标,分析了误差的来源,结合磁干扰、安装误差、不平衡度等提出了综合补偿模型,给出了模型求解方法。同时,采用综合补偿模型对实测数据进行补偿处理并验证。实验结果表明,本文所建立的综合补偿模型适用于实测数据的补偿,能够有效降低外界干扰的影响,提高航磁梯度张量数据的质量,且补偿效果明显。

Abstract：

In the compensation of the aeromagnetic gradient tensor data based on superconducting, the simulation results of the compensation model often differ from the compensation results of the survey data. To establish a model that is valid for measured data, this study analyzed the sources of errors, proposed a comprehensive compensation model by combining magnetic interference, installation errors, and the degree of unbalance, and determined the method to solve the model. Moreover, this study compensated the measured data using the comprehensive compensation model proposed and verified the compensation effects. The experimental results show that the comprehensive compensation model is applicable to the compensation of measured data since it can not only effectively reduce the influence of external interference but also can improve the quality of magnetic gradient tensor data and achieve significant compensation effects.
