Traditional transform algorithm has been improved in this paper. The new efficient algorithm has overcome the troubles of false frequency and port effect existing in traditional transform algorithm. The test of theoretical models and the field seismic data indicate that the improved transform algorithm has the merits of good stability, high reliability and weak distortion, and can efficiently eliminate false frequency and port effect.
