调幅和调频波运动构成反射波地震勘探的地滚波噪音,于是,可以应用一维线性调频匹配滤波来消除趣滚波.这种滤波在地滚波频率区间内、外可有效地使地滚波能量衰减而不损害信号子波。当地震反射与地滚波频带重叠时,这种新滤波方法比常规频率滤波和多道滤波消除地滚波更有效而不影响地震数据的垂直分辨率。 AM and FM waves constitute the ground-roll noise of reflected seismic exploration, so one-dimensional LFM matched filtering can be applied to eliminate the interesting roll-off wave, which effectively makes the ground roll outside and inside the ground-roll frequency range The wave energy is attenuated without damaging the signal wavelet. When the seismic reflection overlaps with the ground roll, this new filtering method is more efficient than the conventional frequency filtering and multi-pass filtering to eliminate the ground roll without affecting the vertical resolution of the seismic data.
