摘要
针对现有的地震子波振幅谱模型的不足提出了新的振幅谱模型及其估计方法。介绍了子波的Z变换在单位园上无零点和子波自相关函数已知的条件下混合相位地震子波估计的方法原理和判别准则 ,并在此基础上提出了基于地震子波振幅谱模拟技术的混合相位地震子波估计方法。合成和实际数据处理结果均表明 。
This paper proposed a new amplitude spectrum model of seismic wavelet and a method for its parameter estimation after an analysis of defect for old model. The methodology and determination criterion for mixed phase seismic wavelet estimation were introduced under the conditions that there are no zeros on the unit circle for z transformation of wavelet and the automation of wavelet is assumed to be known. Then the method for mixed phase seismic wavelet estimation was work out based amplitude spectrum modeling for the seismic wavelet. Synthetic and real data examples demonstrated the effectiveness of the method.
