Abstract：Those elimination is a necessary,there are all kinds of coherent noise on seismic records because of many reasons caused by shooting.propagation and receiving of seismic wave. Aimed at the coherent noise in seismic data processing,the paper presented self-adaptive coherent noise attenuation technique in time-space domain,separating signal noise.The method looks to the apparent velocity,that noise is on whole processing plane,approximately as constant (positive or negative value),which can effectively eliminate the linear noise,surface wave and multiple and has HI-FI signal,that is ideal noise elimination method for seismic data processing in complex area and area having low signal-to-noise ratio, having the advantages of high operation speed and good noise-suppressed effect.
