摘要
逆散射理论作为量子力学发展的产物,目前在地震数据处理方面得到了较为广泛的应用.逆散射成像是通过散射体外部场的探测来获得散射体内部的信息,它是近年来发展比较迅速的一种成像方法,其突出的应用是运用逆散射序列中的一阶近似项进行深度成像.本文对逆散射理论在国内外的发展历程进行较为系统的概括和总结,在此基础上,对逆散射理论的应用前景进行了分析.逆散射理论在多次波的压制、界面奇性反演、大扰动深度成像等方面具有广阔的应用前景.
At present, inverse scattering theory （IST）, which comes from quantum mechanics, is widely used in the field of seismic data processing. Inverse scattering imaging can obtain the interior information of object by analyzing the exterior field data detected. This is the new and strongly method for geophysicists which know the deep structure in the earth. The development of IST is systematically generalized and summarized in the paper. At the same time, its future application and developing direction are analyzed. IST provides wide reaching field in suppressing multiple, singular inversion of interface, depth imaging of large perturbation model.
