| 摘 要： | 一次波L1范数最小化的多次波自适应相减方法,简称L1方法,是基于匹配滤波器设计的多次波自适应相减算法中的一种常用方法.当一次波和多次波混杂在一起时,L1方法有时会伤害一次波,导致一次波同相轴的连续性变差.本文利用预测误差滤波器度量一次波同相轴的连续性,在L1方法的皋础上,提出一种能够在压制多次波的同时,尽量保持一次波同相轴连续性的多次波自适戍相减算法,简称连续性约束L1方法.利用Pluto模犁数据进行多次波相减的结果表明,连续性约束L1方法能够在有效压制多次波的同时,更好地保护一次波.

| Abstract: | The L1-norm method is one of the widely used matching filters for adaptive multiple subtraction.When the primaries and multiples are mixed together,the L1-norm method might damage the primaries,leading to poor lateral continuity.In this paper,we propose a constrained L1-norm method for adaptive multiple subtraction by introducing the lateral continuity constraint for the estimated primaries.We measure the lateral continuity using prediction-error filters(PEF).We illustrate our method with the synthetic Plut... |
