程序为叠前偏移c语言程序，利用双程波波动方程有限差分法，此程序可以进行大角度成像。还有prestack common-shot split-step Fourier migration源代码-prestack fd migration，The 2-D prestack common-shot split-step Fourier migration

RTm叠前逆时偏移代码和论文 包括代码和论文(RTM prestack reverse time migration code and paper including code and paper)

叠前炮集2D正演和偏移,详细使用信息见说明文档(Prestack gun sets 2D forward and offset. See the documentation for detailed usage information)
