| 摘 要： | 基于运动学原理对转换波DMO脉冲响应近似公式进行修正,从修正后的公式出发推导出一种新的f-k域转换波真振幅DMO算法。脉冲响应曲线的对比表明对脉冲响应近似公式的修正明显减少了误差。理论模型试验结果表明算法具有较高的运动学精度及保幅性能,是一种可靠、理想的转换波DMO算法。

| Abstract: | Based on the principle of kinematics, authors revised the approximate formula of DMO pulse response and proposed a new algorithm to perform true-amplitude DMO for converted waves in f-k domain. The comparison of pulse response curves show that the error of the formula is reduced obviously after the revision. Theoretical model test shows that the algorithm is a reliable and ideal one which has high precision of kinematics and good property of amplitude preservation. |
