Application of the equipoise pseudomultichannel matching filter in multiple elimination using wave-equation method
均衡拟多道匹配滤波法在波动方程法压制多次波中的应用

Single channel least-square matching filtering method can not get good matching filter result when the signal vector(one reflection record) is not vertical with the noise vector(multiple reflection record).In order to overcome the weakness,we propose the equipoise pseudomultichannel least-square matching filter method.It uses the statistical method on the space to make the signal vector be always vertical with the noise vector in the equipoise field.It combines the character that the pseudomultichannel least-square matching filter can do better in waveshape matching.So the method can produce better result.It proves good as it can effectively eliminate the multiples in the single model,SEG/EAGE SMAART model and the actual data.
