航磁补偿就是要去除飞行平台引入的干扰磁场.本文按照磁补偿工作的一般流程介绍了固定翼无人机航磁测量系统的构成、平台干扰源、干扰场建模、补偿飞行方案.在将有人机的磁补偿工作扩展应用到固定翼无人机的过程中,由于固定翼无人机很难进行常规的补偿飞行,没有获得相应数据.但考虑到无人机本身的磁干扰相对较小,而且移动方便,根据对实验区内航磁数据的分析掌握的信号特性,试探性地提出一种基于地面测量的静态补偿方案,初步建立针对低磁无人机平台获取的航磁总场数据补偿的方法,并对以后进一步实验的关键问题进行了讨论.
Aeromagnetic compensation is to remove the interference magnetic field introduced by the flight platform.In this paper, according to the general process of magnetic compensation work, this paper introduces the structure of the aeromagnetic measurement system of the UAV, the interference sources, the modeling of the disturbance field and the compensation flight plan. In the process of using man-made magnetic compensation to extend to the fixed-wing UAV, the fixed-wing UAV is difficult to carry out the conventional compensatory flight and did not obtain the corresponding data.But considering the relatively small magnetic interference of the UAV itself , And it is easy to move. Based on the characteristics of the signals acquired from the analysis of aeromagnetic data in the experimental area, a static compensation scheme based on ground measurement is tentatively put forward. The total magnetic field data acquired for the platform of low magnetic unmanned aerial vehicle Compensation methods, and the key issues for further experiments were discussed.
