  1. The differences between this method and other similar methods are : ( 1 ) the fast synthetic source record algorithm based on the wave theory is adopted in prestack depth migration. ( 2 ) the plane wave source is used in migration that is consistent with the velocity analysis method. ( 3 ) by using the controlled illumination, the distortion of the plane wave source wavefield due to the lateral velocity variation is avoided therefore the error of velocity analysis is reduced and ( 4 ) the practical velocity spectrum makes the interactive migration velocity analysis feasible and convenient

    與其他類似偏速度分析方的不同點在於: ( 1 )疊前深度偏採用基於波理論的快速合成記錄演算; ( 2 )偏採用平面波,與速度分析方一致; ( 3 )應用控制照明技術,避免了因橫向變速而導致的平面波波場在傳播過程中的畸變,從而減小了速度分析的誤差; ( 4 )實用的速度譜設計,使交互偏速度分析可行且易於操作。
