基于α-trimmed矢量中值滤波压制同步激发邻炮干扰

Suppression of crosstalk from simultaneous sources with alpha-trimmed vector median filtering

本文提出的α-trimmed矢量中值滤波属于压噪类算法,相对于矢量中值滤波,该方法在压制邻炮干扰的同时,能更好地保留主炮能量;相对于迭代反演算法,具有更高的计算效率,从而满足海量数据的处理需求,并且该方法有很好的鲁棒性,可以适用于各类数据。合成数据和实际数据的试验结果表明了该方法的有效性。

Theα-trimmed vector median filtering(ATVMF)p roposed in this paper is a kind of noise attenuation algorithms.Compared to vector median filter(VMF),the ATVMF can preserve the energy o f the current shot as much as possible when suppressing the crosstalk from adjacent shots.Compared to the iterative inversion algorithms,this method is more efficient and robust.Tests on synthetic and field data prove the effectiveness of this method.
