Unmanned helicopter aeromagnetic measurement system and its application

笔者介绍了一种基于无人直升机平台的航磁测量系统的集成与应用。通过对无人直升机飞行平台的集成改装和飞行测试试验,成功将航空磁测传感器与无人直升机平台集成为无人直升机航磁测量系统。为验证系统的有效性,该系统先后完成了航磁补偿飞行和测区应用飞行。通过将实测飞行的数据绘制航磁异常等值线图与测区内以往地磁异常等值线图对比,结果显示两者反映的测区地磁场特征形态基本一致。无人直升机航磁测量系统为地形起伏、环境复杂的勘探区域开展航磁测量提供了一种高效、便捷的工作手段。

This paper introduces the development and integration of the aeromagnetic measurement system for unmanned helicopters.Through integrated assembly testing for unmanned helicopter flight platform and aeromagnetic survey instrument and its magnetic interference testing and magnetic compensation testing,successfully integrate the aeromagnetic instrument with the unmanned helicopter flight platform to develop an aeromagnetic measurement system for unmanned helicopters. The system has completed flight test and flight application work. Compared with the contour map of previous geomagnetic anomalies in measuring area,the reflected geomagnetic field characteristics in aeromagnetic anomaly contour map obtained in flight application are basically the same which proves the effectiveness of the system. The unmanned helicopter aeromagnetic measurement system provides an efficient,convenient and scientific means of work for small exploration blocks with complex topography and harsh environment which need to be carried out aeromagnetic measurements survey.
