摘 要:利用小波变换对重磁异常的奇性作了分析,提出了能刻划三维重磁异常特征的奇性指标.作为新的解释参数,利用它对异常作了深度反演的研究.
Abstract: The singularity of gravity/magnetic anomalies is analysed using wavelet transform inthis paper.Based on this,we proposed the singularity indicator as a new interpretativeparameter because it can describe the characteristics of gravity/magnetic anomalies profound-ly.As an example,we used it to inverse the top depth of a rectangular prismatic body,andgave an explicit formula to calculate the top depth.
