摘要
本文应用高斯束方法合成具有任意变曲界面的非均匀层状介质的二维地震记录,并针对高斯束方法在地面地震和 VSP 应用中存在的假象和失真问题,提出了选择参数的自适应办法及终点选择办法,从而避免了假象和减小失真。
Two-dimensional seismogram in inhomogeneous layered medium in which there are arhitrary curved interfaces can be synthesized by using Gaussian beam method.Self-adaptive and terminal point methods for parameter choice are used to avoid false appearance and to reduce distortion in the application of Gaussian beam technique to surface seismic and VSP data.
