摘　　要：近年来,无人机航空物探已在我国铀资源、金属与非金属矿产资源勘查等多个领域得到了广泛应用,并发挥了重要作用。为提升航空物探自动化作业能力,降低安全风险,开展了基于Z-5B型无人直升机的航空物探(磁/放)测量技术研究工作,攻克了无人直升机航磁航放测量系统集成改装、沿地形起伏飞行作业、无人直升机航磁补偿和无人直升机航放系统校准等关键技术。在松辽盆地北部地区开展了面积性测量试验飞行工作,各项技术指标满足规范要求,试验结果表明:该系统在航速54 km·h^(-1),飞行高度100 m时具有较好的探测能力,可清晰查明地表放射性场分布和磁场特征,圈定异常范围,且具备缓起伏地形条件下仿地飞行的作业能力,可满足现阶段小面积测量作业任务需求,具备生产作业能力。In recent years,unmanned aerial vehicle(UAV)geophysical exploration has been widely applied and played an important role in the exploration of uranium resources,metallic and non-metallic mineral resources,and other fields in China.In order to enhance the automated operation capability of aerial geophysical exploration and reduce safety risks,study on aerial geophysical(magnetic/release)measurement technology based on Z-5B unmanned helicopter has been carried out.Key technologies such as integrated modification of UAV magnetic/release measurement system,flight operation along terrain undulations,UAV magnetic compensation,and calibration of UAV magnetic/release system have been overcome.Areal measurement test flights were carried out in the northern region of Songliao basin,and various technical indicators met the regulatory requirements.The test results showed that the system has good detection ability at a speed of 54 km·h^(-1) and a flight altitude of 100 meters,which can clearly identify the distribution of surface radioactive fields and magnetic field characteristics,delineate abnormal ranges,and has the ability to simulate ground flight under gently undulating terrain conditions.Therefore,the UAV magnetic/release measurement system can meet the current needs of small-scale measurement and has production operation capabilities.
