Multiscale edge models of gravity anomalies for homogeneous sphere and several 2D regular bodies are derived based on the potential wavelet.The features of these models are analyzed and then a mutliscale edges based on the method is put forward for the gravity anomaly inversion.The outstanding ability of the proposed method is that geometric parameters and density parameters can be inverted without any hypothesis.This method also has high stability and good antinoise performance.Finally,a model of 2D block is used as an example to verify the method.
