FONT-SIZE: 14pt">face="Times New Roman">Radon transform is an important data processing method in geophysics field. There are mainly three traditional methods: t-x method, F-K method, and F-x method. Comparing with other recently developed methods, traditional methods have advantages of stable and less computation and still play an important role in real data seismic processing. In this paper, based on the characteristics of radon transform in F-x field, the authors improve F-x methodfont-family: ’Times New Roman’; mso-hansi-font-family: ’Times New Roman’">’face="Times New Roman">s computation efficiency by rewriting the form of matrix and vector’s multiply into the form of vector and vectorfont-family: ’Times New Roman’; mso-hansi-font-family: ’Times New Roman’">’face="Times New Roman">s convolution, and making use of FFT algorithm to implement fast convolution.fix = o ns = "urn:schemas-microsoft-com:office:office" />
