Abstract：Based on the basic principle of seismic trace reconstruction by parabolic Radon transform (PRT) and basic nature of Fourier transform spectrum, the paper presented iteration plus trace e- qualization parabolic Radon transform method that combines the trace equalization technique with band-limited PRT method, which not only greatly improves computational efficiency of interpolation reconstruction of missing seismic trace,but also is successfully used for anti-alias re-sampling processing in prestack seismic data. In comparison with traditional least square parabolic Radon transform, the method has equal computational precision but the efficiency increases by a factor of about 5. The theoretical model test and real seismic data processing showed that the method is characteristic of high precision and high efficiency.
