点源波场记录可以分解成平面波分量,各个分量对应于不同的传播角。这种平面波地震记录比点源球面波记录的结构简单得多,因此是应用于预测反褶积、偏移、反演等许多地震数据处理步骤的理想方法。完成平面波反褶积需要在离散数据域计算拉东变换。直接用积分法求解地球物理问题不能成功地补偿实际数据采样和有限孔径。本文介绍一种通过时空域的
Point source wavefield records can be decomposed into plane wave components, and each component corresponds to a different propagation angle. This kind of plane wave seismic record is much simpler than the point source spherical wave record, so it is an ideal method applied to many seismic data processing steps such as predicting deconvolution, migration and inversion. Completion of plane wave deconvolution requires the calculation of the Radon transform in the discrete data domain. The direct integration method to solve geophysical problems can not successfully compensate for the actual data sampling and finite aperture. This article describes a through space-time domain
