Abstract:We propose the correlation method for estimating the magnetization direction of magnetic bodies under the influence of remanent magnetization. First, we determine the parameter range of magnetic inclination and declination, obtaining a serious of values of the magnetization direction at equal intervals. Then, the measured magnetic total field anomalies are transformed into the reduced-to-the-pole data according to the different magnetization directions. Finally, the cross-correlation between the reduced-to-the-pole data and the normalized source strength data is solved. The theoretical magnetic total maximum correlation coefficient is regarded as the estimated total magnetization direction. Simulation and experimental results show that: this method can effectively estimate the magnetization direction of the magnetic bodies, especially when the magnetic total field anomalies are approximate equiaxial.
