一个原因是被用来追踪雷暴的雷达只可以发现大气中凝结成云或雨滴的水，因为水能以这样的形态反射波束。
One reason is that radars used to track storms can detect water in the atmosphere only once it has condensed into clouds or raindrops, and thus reflects the beam.
该算法使用射线追踪计算传播时间，应用波场界面方程计算反射振幅。
This algorithm USES ray tracing to calculate traveltime, and DE - rives reflection amplitude from wave field interface equation.
此法以反射地震资料中的观测初至旅行时与模型射线追踪旅行时之差的最小平方法为基础。
It is based on the least square of the difference between the real reflection first break time and corresponding modeled ray-tracing travel time.
