Title: 多维向下向下反卷积的海底地震数据表示法：理论与实际意义

Abstract: Multidimensional up-down deconvolution effectively eliminates surface-related multiples from ocean-bottom seismic data. Recently, several down-down deconvolution methods have been introduced as attractive alternatives. Whereas multidimensional up-down deconvolution fully accounts for lateral variations of the medium parameters, the underlying theory of some of the down-down deconvolution methods is essentially based on the assumption that the medium is horizontally layered. We derive representations for multidimensional down-down deconvolution for laterally varying media in a uniform manner and discuss the pros and cons of the various methods. Show Chinese abstract

Abstract: 多维上下解卷积有效地消除了海底地震数据中的与地表相关的多次波。 最近，几种下下解卷积方法被引入作为有吸引力的替代方法。 尽管多维上下解卷积充分考虑了介质参数的横向变化，但一些下下解卷积方法的基本理论本质上是基于介质为水平层状的假设。 我们以统一的方式推导出横向变化介质的多维下下解卷积表示，并讨论各种方法的优缺点。
