Abstract

By using a new interpolation method based on Discrete Fourier Transform (DFT), we have got the goal of the separate seismic track interpolation. The new approach fully employs the characters of DFT, and it is excellent in many respects, such as, it is in no need of any interpolating function; the arithmetic is simple so as to suit to the immense seismic data processing; it is of high precision with the relative error at about ten million to one; high fidelity reconstruction without negative effect to the subsequent processing; good practicability and can serve the oil production. Quite good outcome has been obtained in practical data processing. The experimental results illustrate the effectiveness of the new interpolation method in solving the insufficiency of sampling.
