Abstract: To longer strike structure in face,the data processing of electromagnetic wave tunnels transmit is a complex problem. Either in traditional hand interpretation or in modern tomography, both could not obtain better effects. On the base of the tomography, using some particular processing technique, sach as horizontal correlation enhancement and anomaly enhancement et al., can obtain better effects and have more high resolution and stability, are easer to geologic interprotation. The effects of the model computation and the practice are given in the paper.
