【摘要】 反Q滤波的目的是消除地震波在传播过程中的振幅衰减和相位畸变,使信号高频成分得到恢复,从而提高地震资料的分辨率。反Q滤波受多种因素影响,如稳定性、噪声和Q值误差等。从反Q滤波公式出发,对反Q滤波的影响因素进行了讨论,给出了相应的改进方法。更多还原

【Abstract】 Inverse Q filtering is to compensate the amplitude attenuation and correct the phase distortion.With the restoration of high frequency content,the resolution of seismic data improves.Many factors affect inverse Q filtering including stability,noise,Q error.This paper put forward some measures to improve inverse Q filtering.更多还原
