应用倾斜叠加滤波压制海上线性干扰

摘要

Information from earthquake exploration is full of linear interference,which will impact the signal noise ratio of the information.The traditional method to remove it is to use F_K transformation method,but this method is easy to get space false frequency.This paper discusses how to remove linear interference by inclined superimposed transformation method.After this method is used offshore and on the land,the linear interference of straight section and superimposed section is removed well.%地震勘探采集的资料含有很强的线性干扰,严重影响地震资料的信噪比。传统的压制线性干扰的方法是用F_K变换方法,但容易产生空间假频。研究采用倾斜叠加变换方法压制线性干扰,该方法应用于海上、复杂陆地地震资料后,其单炮和叠加剖面的线性干扰都得到了很好压制。
