匹配滤波法在大炮检距资料处理中的应用

The application of matching filter method in cannon offsel data processing.

在进行高分辨率地震资料处理时,长排列资料往往会出现大炮检距的波组低频化现象,使得地震剖面的分辨率降低。提高分辨率是目前高分辨率处理中的一个难点,针对这一难点提出了匹配滤波法处理技术。介绍了该技术的主要处理步骤,并利用数学模型和实际资料进行了匹配滤波法处理和常规处理的对比,处理结果表明,匹配滤波法有效地提高了分辨率。

Long array data will present cannon offset and low frequency wave in high resolution processing, reduce the resolution of seismic section. The problem is one of the improve resolution in high resolution processing. The paper presents the match filter processing method aim at it. Expatiation the main processing step. Comparisons with Matching filter the conventional processing. Processing result show matching filter method improves to resolution effectively.
