主 题：Multiple adaptive matching filter equipoise pseudomulti-channel Huber norm second-order derivative
摘 要：This study is aimed at improving multiple adaptive *** propose a modified pseudomulti-channel matching method based on the Huber norm,to adjust the matching differences on frequency and phase between the predicted multi-ples and original *** second-order derivative of the predicted multiples is utilized to replace the derivative of its Hilbert *** to the additional frequency term,this method can enhance the high-frequency *** introduce 180◦phase rotation of the multiple channels,which can decrease phase *** Huber norm interpolates between smooth L2 norm treatment of small residuals and robust L1 norm treatment of large *** method can eliminate the restriction of large value conditions from the L2 norm and weaken the condition of orthogonality from the L1 *** applications of the Pluto and Delft models shows that compared with pseudomulti-channel matching filter,the main frequency is increased from 36 Hz to 38 Hz,and the primary reflection wave is more *** practical application of field data verifies the effectiveness of the proposed method.
