基于l1/l2范数的表面多次波自适应相减方法
Keywords: srme,自适应相减,l1范数,l2范数,gpu
Abstract:
？依据l1和l2范数自适应相减方法的特性,提出了联合l1/l2范数的表面多次波自适应相减方法,并引入gpu并行加速,在充分发挥两种方法优势的同时,有效缓解了两种自适应相减方法限制性条件引发的问题,在较短的时间内获得收敛的维纳滤波器,并且较好地拟合多次波模型和原始记录中的多次波.文中方法无需l2范数方法的假设条件,相比于l1范数方法提高了计算效率.理论模型和实际海洋地震数据测试表明,基于l1/l2范数的gpu并行加速的表面多次波自适应相减方法可有效压制地震数据中的表面多次波.
