Random noise is a kind of noise which is hard to advoid in seismic exploration��and it is greatly decreased signal-to-noise ratio of seismic meterials��resulting in poor or no migration imaging�� Adaptive predictive filter method updated AR model formula under the assumption of AR model factors change in t-x domain��then introduced cost function to improve the stability and uniqueness of the solution and got 1D and 2D pressing noise recursive formula�� Synthetic and real data examples showed that adaptive predictive filtering pressed the random noise interference in signal-to-noise ratio data and protected effective seismic wave well��
