| 摘 要： | 对于大多数采用可控震源激发的应用实例而言,一般都要采用噪音剪辑的手段,在强背景干扰情况下更应如此,变权叠加(Diversity Stack)方法即提供了这样一种数据采集的去噪手段。当干扰背景出现变化时,变权叠加方法对信噪比的改善明显优于常规的垂直叠加方法;当干扰背景没有变化时,变权叠加方法也不存在风险。本文从理论上介绍了变权叠加技术,并将变权叠加与垂直叠加作了比较。

| Abstract: | Noises of data acquisition must be edit out when using vibroseis to do exploration under strong back-ground interference . Diversity stack is a kind of method to eliminate noise. From the analysis of S/N we know:It's more effective by use of diversity stack than vertical stack if the background interference is changed. There is no risk for diversity stack if the background interference isn't changed. This paper in-troduced diversity stack from it's theory and made a compare between diversity stack and vertical stack. |
