谱迭加(Spectral stack)Michael O.Marcous and Lee Kok Moo,Digicon Exploration,Singapore。(S3.l) 地震反射资料的成象有两种基本方法.最普通的方法包含正常时差校正(NMO)和共深度点(CDP)道集迭加,而其它方法则包括用标量波动方程获得的算子对共震源和接收道或共编移道进行聚焦。已经求出地震成象的一种补充形式,它具有每一种标准方法的部分特点。进行NMO和迭加处理时不是使用一组记录,而是用它的空一时付氏措(或者谱记录)来产生零偏移记录道的话估计。于是,上述谱迭加道的时间逆变换显示
Spectral stack Michael O. Marcus and Lee Kok Moo, Digicon Exploration, Singapore. There are two basic approaches to the imaging of seismic reflection data (S3.1). The most common methods include normal time difference correction (NMO) and CDP gathers superposition, while others include scalar wave equation The operator of the co-seismic source and receiver or co-channel alignment focus. A complementary form of seismic imaging has been derived that has some of the features of each of the standard methods. Instead of using a set of records for NMO and overlay processing, estimation is made using its spatio-temporal measures (or spectral recording) to produce zero-offset traces. Thus, the above-mentioned spectrum of time inverse transform display
