抛物 Ｒadon 域地震干涉技术

当地震干涉技术应用在不完整数据体上时，缺失的地震记录会在合成的虚炮集记录上造成大量的假象。为减少假象的产生，笔者将抛物 Ｒadon 变换与地震干涉技术相结合，在抛物 Ｒadon 域中应用地震干涉技术。本文通过数值模拟验证了抛物 Ｒadon 域地震干涉技术的有效性，并将该方法应用在不完整数据体上。结果表明，抛物 Ｒadon 域地震干涉技术可以有效减少假象的产生，并能够压制缺失的地震数据的影响，提高虚炮集记录的质量。

Seismic interferometry in parabolic Radon domain

When seismic interferometry is applied to incomplete data，the missing part will cause spurious events in virtual source gather． In order to suppress these spurious events，the authors combine the parabolic Ｒadon transform with seismic interferometry，and apply seismic interferometry in parabolic Ｒadon domain． The effective- ness of seismic interference technique of parabolic Ｒadon transform has been verified through numerical simulation， and the authors apply this method to incomplete data． The results show that the parabolic Ｒadon domain seismic in- terferometry can reduce the spurious events and suppress the effect of the missing part of data． The virtual source gathers obtained by parabolic Ｒadon domain seismic interferometry can also be improved．
