实时相关叠加器的噪声控制系统设计

Design of noise controlling system in realtime correlation stacker

实时相关叠加器的噪声控制系统是可控震源地震勘探中必不可少的重要部分,噪声控制系统是指对原始记录信号的噪声进行压制,提高记录的信噪比。在数据相关之前,剔除突发性噪声、尖脉冲或脉冲串等噪声能量占压倒优势的数据,从而得到高保真度的地震勘探资料。

The noise controlling system of real time correlation and stack is a very important part in vobroseismic prospecting.Its aim is to suppress the noise in original signals and enhance the signal-to-noise ratio.Before correlation,the system first takes out the data of great noise,and then,the high fidelity seismic data can be obtained.
