【摘要】 地面高精度磁法的优点是可以开展大比例尺作业,可以高分辨率地反映地面的地质效果,缺点是采集效率太低；航空磁测的优点是采集效率高,缺点是受飞行高度的影响,反映的地质效果分辨率太低,且无法开展大比例尺工作。作者提出了一种折衷的方案,采用无入直升机作为载体的UAV航磁系统,既能够快速、高效、高精度定位采集数据,大比例尺地开展作业,又能高分辨地反映地面的地质效果,同时还能够消除地面地表等干扰物和起伏地形产生的影响。UAV航磁系统在国外的研究已经趋于成熟,很多物探公司已经用于商业运作,在国内的研究还刚刚起步,很少看到国内的相关报道。论文巧妙地利用无人机控制理论相关技术,借助无人机磁航向系统测量地磁场三分量值,姿态控制系统测量飞机的姿态角,提出了事后补偿的方法。论文介绍了无人机及飞行平台系统和自动控制系统,研究了UAV磁干扰的类型和性质,建立了数学模型,阐明了磁补偿的基本原理,给出了具体的补偿方案,并仿真进行了实验,证明了UAV航磁系统的可行性。更多还原

【Abstract】 Ground high-precision magnetic method can carry out large scale magnetic survey work and provide high-resolution image map of the geomagnetic field.Since walking is too slow,data collection efficiency of this method is too low;Aero-magnetic can collect data efficiently,but due to safety flight,this method can not provide high-resolution image map of the geomagnetic field,and can not carry out large scale magnetic survey mission.The author give a compromise proposal.UAV aero-magnetic system of using UAV as carrier can collect data more quickly, efficiently and accurately,and can carry out large scale magnetic survey mission and can provide rovide high-resolution image map of the geomagnetic field,in addition to eliminate the effect of magnetic interferences and rugged terrain.The reserach of UAV aeromagnetic system has been proved to be successful,some company of geophysical has carried out magnetic survey mission and obtained great results.Domestic research of UAV aeromagnetic system has just set up the project,some relevant information rarely has been reported.The papers uses UAV realted technology of UAV control theory,measures third-components of geomagnetic field by magnetic heading system of UAV,measure attitude angle of UAV by Inertial Naviagtion System(INS),and gives magnetic compensation method.The paper introduces the platform system and automatic flight control system of UAV,study type and nature of magnetic interferences,constructs mathematical model,illustrates the basic principle of magnetic compensation,gives specific compensation proposal,does simulation experiments,and analysis the feasibility of UAV aero-magnetic system.更多还原
