摘要
根据Radon变换理论,结合平面映射、推导了双曲Radon正反变换公式,从而使Radon变换沿直线倾斜叠加推广到双曲Radon变换沿双曲线叠加。双曲Radon变换更加有利于地震数据处理,可减少变换噪音和能量弥散,从而提高资料处理质量。文章还阐明了双曲Radon变换可用于处理垂直地震剖面的上、下行波场分离及提取地面地震资料不同速度波型的波等方面的问题;并对简单的射线模型资料进行了计算,结果较好。
In this paper, the formulas of forward hyperbola Radon transform and inverse hyperbola Radon transform are deduced on the basis of Radon transform's principle, and stack along a constant slope in Radon transform is extended to stack along hyperbola in hyperbola Radon transform. Therefore, the hyperbola Radon transform is capable of lessening both transform's noise and energy spread and, thus, improving transform results in seismic data processing. It is favorable for separating up-down going wavefields in VSP. and picking up different speed wavefields in HSP. Besides, a theoretical data of VSP is processed.
