Wavelet processing is an effective method to improve the resolution of seismic data. The key is to obtain accurate wavelet estimation. Based on the properties of signal phase information preserved in high-order cumulants, a wavelet estimation method based on bispectrum of seismic signals is given. Theoretical calculations are carried out for seismic wavelets with different properties. The results show that this method It works. At the same time, the processing of field seismic data also shows the potential of signal high-order spectral techniques to improve the resolution of seismic data wavelet processing
