摘　　要：子波处理技术是提高地震资料分辨率的一种有效方法 ,其关键在于获得准确的子波估计。本文根据高阶累积量中保留有信号相位信息的性质 ,给出了一种基于地震信号双谱的子波估计方法 ,并针对不同性质的地震子波 ,进行了理论计算 ,结果表明这一方法是可行的。同时 。Wavelet processing, in which wavelet estimation is essential, is an effective technique for improving the resolution of seismic data. Based on the fact that higher order accumulation retains the phases of signal information, a method of wavelet estimation using bispectrum of seismic signal is developed in this paper. The examples of synthetic data with different phase property of wavelet show that the method is feasible, and the examples of field data also show that the higher order spectra of signals are promising in wavelet processing and resolution improvement.
