图2 合成的X-T域(a)与转换到R-T域(b)的CMP道集 X-T域的径向射线(红色虚线)上的A、B两点映射为R-T域同一视速度(1 000 m/s)上的C、D两点

Fig.2 A synthetic CMP gather in the X-T domain(a) and transformed into the R-T domain(b) Points A and B on the radial ray(red line) of the X-T domain are maps of points C and D on the same apparent velocity(1 000 m/s) of the R-T domain
