anticlockwise revolution

With a nonuniform spatial sampling,reverse time migration imaging algorithm is presented in this paper.

提出了一种冲激脉冲表层穿透雷达(ImpSPR:Impulse Surface Penetrating Radar)非均匀空间采样下的逆时偏移(NUSS-RTM:Non uniform Spatial Sampling Reverse Time Migration)成像算法。

Prestack reverse time migration requires computing the first breaks time of imaging points.

叠前逆时偏移需要计算成像点的初至时间。

Based on Snell s law, an approach for calculation firstarrival travel times in a transverse isotropic media is developed, of which result can be used as the imaging condition of reverse time migration.

从snell定理出发,采用插值法求取网格空间中各点的直达波旅行时,以此作为弹性波逆时偏移的成像条件,实现多波多分量资料的逆时偏移。
