High-Precision Source Positions Obtained by the Combined Inversion of Different-Order Local Wavenumbers Derived from Aeromagnetic Data

The aeromagnetic survey is a common remote sensing tool for detecting iron deposits. local wavenumber of magnetic anomaly used to interpret the edges or positions sources, and can involve first- second-order wavenumbers. In this paper, we derived linear equation between source location; therefore, propose constraint first Tests on synthetic data show that parameters, computed using combination equations involved different-order wavenumbers, are closer true values smaller spread in estimated values. For gridded data, proved allowed us accurately estimate position. When applied from Hebei province, China, refined location most features, which interpreted as possible
