航磁补偿技术及补偿质量的评价方法

航磁补偿的目的是要消除飞机平台引入的干扰磁场,对于高精度航空磁探来说,磁补偿质量直接制约了探测效果。文章按照航磁补偿的执行步骤进行了飞机平台磁干扰建模、模型参数求解方法、补偿飞行方案。另外,为了对补偿飞行的质量进行有效控制,采用量化指标对磁补偿效果进行评价,判定补偿效果的优劣。最后,基于 MFC软件平台开发了航磁补偿系数求解及补偿质量评价软件。

Investigation of Aeromagnetic Compensation Technology and Performance Assessment Method

The purpose of aeromagnetic compensation is to eliminate magnetic interference introduced by the aircraft plat.form. For high-precision aeromagnetic exploration, the quality of aeromagnetic compensation directly restricts perfor.mance of exploration. According to the implementation steps of aeromagnetic compensation, in this paper, the modeling ofaircraft magnetic interference was built, the method of solving the model parameters and the calibration flight plan wereput forward. Further, in order to effectively control quality of compensation flight, the quantitative indicators were used toevaluate the effects of aeromagnetic compensation, compensation effect of judging the merits. Finally, based on MFC soft.ware development platform, the coefficient solver and performance assessment software for aeromagnetic compensation wasdeveloped.
