Transient electromagnetic data multi-attribute fusion technique

The invention discloses a transient electromagnetic data multi-attribute fusion technique, which comprises the steps: S1, carrying out standardization on transient electromagnetic data attributes; S2,performing inter-attribute correlation analysis on the standardized data attributes in the step S1, and judging whether PCA dimension reduction processing is suitable for being performed or not; S3,solving a feature value and a feature vector of the attribute suitable for PCA dimension reduction processing in S2; and S4, performing principal component extraction according to the feature value and the feature vector obtained in the S3. According to the invention, different interpretation methods of explored results caused by different transient electromagnetic exploration devices are avoided,and the anomalies obtained by different devices are unified; and five other attributes except the resistivity are added to solve the problem of spatial change of the resistivity caused by the water-containing geologic body, th
