Three-dimensional (3D) gravitational and magnetic exploration is performed using aerial measurement tools, however, this has difficulties with measuring-height design and the construction of a joint-interpretation scheme. At present, the height in such experiments is set according to the measurement scale, and the distribution characteristics of anomalies are not fully considered. Here, we present the idea of using the attenuation characteristics of a singular-value spectrum to evaluate the contributions of various measurement heights and multi-height combinations for inversion to correctly and reasonably design appropriate measuring heights and the number of various measurement heights to be set. The joint-gradient Euler-deconvolution method can accurately obtain the distribution of geological bodies from 3D gravitational and magnetic data at an improved resolution, and experimental tests confirm these findings. Therefore, an actual 3D aeromagnetic-data-acquisition and inversion test were carried out in the vicinity of the Zhurihe Iron Mine in Inner Mongolia. The flight-height difference was set to 60 m, and the specific distribution of lodes was obtained by the joint-gradient Euler-deconvolution method. This provides a reliable basis for future detailed exploration and proves that the methods presented in this paper have good practical-application effects and prospects.

使用航空测量工具进行三维（3D）引力和磁力探测，但是，这在测量高度设计和构造联合解释方案方面存在困难。目前，这种实验的高度是根据测量规模来设定的，并且还没有充分考虑异常的分布特征。在这里，我们提出使用奇异值谱的衰减特性来评估各种测量高度和多高度组合的贡献以进行反演的想法，以正确合理地设计适当的测量高度和要设置的各种测量高度的数量。联合梯度Euler反褶积方法可以以更高的分辨率从3D重力和磁性数据中准确获取地质体的分布，并且实验测试证实了这些发现。因此，在内蒙古诸日河铁矿附近进行了一次实际的3D航空磁数据采集和反演测试。将飞行高度差设置为60 m，并通过联合梯度Euler-反卷积方法获得矿体的比分布。这为以后的详细探索提供了可靠的依据，并证明本文提出的方法具有良好的实际应用效果和前景。在内蒙古的竹日河铁矿附近进行了实际的3D航空磁数据采集和反演测试。将飞行高度差设置为60 m，并通过联合梯度Euler-反卷积方法获得矿体的比分布。这为以后的详细探索提供了可靠的依据，并证明本文提出的方法具有良好的实际应用效果和前景。在内蒙古的竹日河铁矿附近进行了实际的3D航空磁数据采集和反演测试。将飞行高度差设置为60 m，并通过联合梯度Euler-反卷积方法获得矿体的比分布。这为以后的详细探索提供了可靠的依据，并证明本文提出的方法具有良好的实际应用效果和前景。
