  • The separation of the gravity anomaly using wavelet multiple decomposition and wavelet multiscale edges reconstruction are studied.The vertical and horizontal influence can be separated simultaneously by this method,which provides a reasonable reference for the separation of complex regional gravity anomaly.The gravity anomalies of the Ryukyu subduction zone are separated base on simulation experiment.In the vertical gravity anomalies separation,the separation scales can be determined,based on the correlation between gravity anomaly and topography.Wavelet multiscale edge analysis by selecting appropriate scales range can achieve the effect of gravity horizontal separation,which is simpler than multiscale edges reconstruction.The data used to inverse structure of the subduction zone can be got through the separation.

Abstract: The separation of the gravity anomaly using wavelet multiple decomposition and wavelet multiscale edges reconstruction are studied.The vertical and horizontal influence can be separated simultaneously by this method,which provides a reasonable reference for the separation of complex regional gravity anomaly.The gravity anomalies of the Ryukyu subduction zone are separated base on simulation experiment.In the vertical gravity anomalies separation,the separation scales can be determined,based on the correlation between gravity anomaly and topography.Wavelet multiscale edge analysis by selecting appropriate scales range can achieve the effect of gravity horizontal separation,which is simpler than multiscale edges reconstruction.The data used to inverse structure of the subduction zone can be got through the separation.
