Abstract：The self-adaptive multiple attenuation method is one of these methods that are more characteristic.Applying the prediction-minus technique to attenuate surface-correlated multiple, the method needs making inversion of wavelet by principle of minimum energy.The paper introduced the principle of the method in detail and proposed a fast and effective algorithm.Using SINC interpolation in frequency domain can determine wavelet form in sparse frequency points since length of wavelet is greatly shorter than that of seismic records.The calculation on that basis can greatly reduce the number of inversion parameters,which greatly improved the precision and speed of the method.
