摘　　要：为解决地面人员难以到达的特殊区域大比例尺磁测数据获取问题,本文提出一种基于三轴磁通门传感器,采用旋翼无人机进行航空磁测的方法.项目组研制适合旋翼无人机搭载的航磁数据记录仪,并完成旋翼无人机、三轴磁通门传感器、航磁数据记录仪的集成工作,开展了三轴磁通门传感器安装点位噪声水平试验、地面空中对比试验、磁性体识别试验、动态飞行一致性试验、区域飞行试验.旋翼无人机航磁系统具有操作简单、设备轻便、效率高的特点,能在地面人员难以达到的区域开展低空航磁测量.中国四川省黑竹沟地区是地磁异常区域,项目组在该区域内的沟壑、峡谷、湖泊等实地开展了野外应用测试,完成了这些特殊区域的航磁调查工作.To deal with the problem of large-scale magnetic surveys in areas difficult to reach by ground personnel,an aeromagnetic survey method based on the 3-axis fluxgate sensor and using rotorcraft Unmanned Aerial Vehicles(UAV)is proposed in this paper.The project group developed aeromagnetic data recorder suitable for the rotorcraft UAV and completed rotorcraft UAV,3-axis fluxgate sensor and aeromagnetic data recorder integrated.Tests have been made to installation point noise level of the 3-axis fluxgate sensor,ground-air contrast,magnetic object identification,dynamic flight consistency,and area flight.Aeromagnetic surveys based on rotorcraft UAV have the advantages of simple operation,light equipment and high efficiency.Low-altitude aeromagnetic surveys can be done in the areas where people are difficult to reach.The Heizhugou,located in Sichuan of China,is a geomagnetically abnormal area,where the project group carried out the application tests over various units such as gullies,canyons and lakes,and completed aeromagnetic survey investigation in these particular places.
