本文绘出了一种非线性Radon变换正反投影公式。这种变换比常规Radon变换具有更广泛的用途。文中探讨了这种变换在地震数据处理中的某些应用, 并用这种非线性Radon变换进行了非零偏移距的VSP波场分离处理, 效果较好。

In this paper,both forward and inverse projcction formulae of a non-linear Radon transform,which proved to have a wider use than the conventional Radon transform (linear Radon transform),are presented. And the use of the transform under some cases is also detailed. The sepcration of nonzero offset VSP wavefield using the proposed transform has yielded satisfactory results.
