多次反射通常被认为是噪声，并且已经开发了许多方法来衰减它们。然而，与一次反射类似，多次反射是由地下反射器产生的，并包含它们的反射率信息。我们可以对曲面相关的倍数进行成像，以对应的质点为源。传统的源-接收机迁移假定源i是一个脉冲函数。本文推广了任意源的源接收机偏移，并将其应用于多次反射的偏移。使用一个复杂的合成数据集来测试该理论。结果表明，多重偏移算法对多重污染数据的成像是有效的。
Multiple reflections are usually considered to be noise and m any methods have been developed to attenuate them. However, similarly to primary reflec tions, multiple reflections are created by subsurface reflectors and contain their reflectiv ity information. We can image surface related multiples, regarding the corresponding pr imaries as the sources. Traditional source-receiver migration assumes that the source i s an impulse function. I generalize the source-receiver migration for arbitrary sources , and apply it to the migration of multiple reflections. A complex synthetic dataset is used to test the theory. Results show that my multiple migration algorithm is effective for imaging the multiple-contaminated data.
