Wave equation migration after common receiving point slant stacks (WEMCRPSS) is essentially a prestackmigration method.
共接收点倾斜叠加波动方程偏移，本质上是一种叠前偏移方法。

Prestackmigration of common shot records is very sensitive to the velocity input, and demands a kind of continuation formula which can adapt to both vertical and lateral velocity variations.
共炮记录叠前偏移对输入的速度非常敏感，要求偏移中所使用的延拓公式能较为精确地适应速度的纵横向变化。

Therefore, this paper introduces a method of prestack time migration in dealing with such a mass of data.
