摘要
本文采用相位移法进行平面波偏移,标量波动方程进行适当的变换,由平面波的成像条件推导出相位移的公式,然后将波场逐层向下延拓得到偏移结果。
In this paper,the plane-wave migration is done using the phase shift method. The result can be attained by transforming the wave-equation suitably, deriving the formula of phase shift from the imaging condition of plane-wave and extending the reflected wave field downward.
