The correlation imaging method is mainly used to solve the location of anomalous source space, but its imaging results are not ideal, and there is divergence in the longitudinal direction. Due to the confirmatory effect of forward modeling on imaging, this paper designs a simple model and multiple anomaly source overlay models. The traditional imaging methods based on Pearson similarity algorithm and cosine similarity algorithm are studied. It is pointed out that Pearson similarity is used to calculate gravity anomalies in traditional correlation imaging. The phenomenon of false anomalies occurs, the related imaging based on Tanimoto similarity is proposed, and the kernel function is improved for the algorithm. The research shows that the method proposed in this paper has an improved vertical and horizontal resolution of the source compared with the traditional correlation imaging method, and the abnormal source form outlines the accurate features, which provides powerful information for the interpretation of gravity data.
