自从南中国海域与国外石油公司合作进行地球物理勘探以来,一些公司用最佳加权迭加的处理方法,对克服海底多次反射的干扰颇有效果。我们曾询问有关处理方法,但对方以技术专利为理由不肯告诉。现参阅国内外有关文献,初步推导出数学模型和试算了多次波衰减曲线,写出来以供大家参考。最佳加权迭加实际上是最佳滤波的简化,本文就从多道最佳滤波谈起。 Since geophysical exploration was carried out in cooperation with foreign oil companies in the South China Sea, some companies used the best weighting superposition method to deal with the problem of overcoming the interference of multiple reflections at the seafloor. We have asked about the handling method, but the other party refused to tell on the ground of technical patents. Now refer to the relevant literature at home and abroad, initially derived mathematical model and trial multiple attenuation curve, written out for your reference. Optimal weighted superposition is actually the best filter to simplify, this article talked about from the multi-channel best filter.
