摘要
《航空磁测技术规范》(DZ/T 1402-2010)对航磁软补偿质量给出了具体的指标要求,但没有明确航磁软补偿质量的评价方法,笔者在借鉴航磁自动数字补偿仪DSC-1的评价方法基础上,提出利用补前磁总场和补后磁总场进行事后评价的方法,并编制了软件,为软补偿质量的统一评价提供了可能。
The criterion of aeromagnetic survey( DZ /T 1402-2010) provides specific measures for assessing the performance of digital magnetic compensation; nevertheless,it does not define the method of quality assessment. On the basis of the quality assessment method for aeromagnetic compensation apparatus( DSC-1),this paper proposes post- assessment method using uncompensated and compensated magnetic fields. The authors have also developed the performance assessment software for digital magnetic compensation on GeoProbe platform,which proves to be a valid tool to give uniform performance measures for digital magnetic compensation.
