本文介绍了一种常规时变、带通滤波处理方法通过标定参考算子的振幅谱频率,求得了滤波截止频率随时间的变化,根据傅里叶变换的标定特怀,此频率标定实际上是由参考算子的简单时间域标定来完成的。该算子乘以常数值后,压缩了参考算子,然后获取地震记录的采样点滤波算子。因此,滤波算子的长度随截止频率而变化,带通随时间而变化。截止频率越高,带通越宽.算子长度越短。该算法没有涉及任何复值运算。如果使用小型计算机,复值运算可 This paper introduces a general time-varying, band-pass filtering method by calibrating the reference spectral amplitude of the reference operator, obtained the filter cut-off frequency with time, according to the Fourier transform calibration Tecla, this frequency calibration is actually This is done by a simple time domain calibration of the reference operator. The operator is multiplied by a constant value, the reference operator is compressed, and then the sample point filter operator of the seismic record is obtained. Therefore, the length of the filter operator varies with the cutoff frequency and the bandpass changes with time. The higher the cutoff frequency, the wider the passband, the shorter the operator length. The algorithm does not involve any complex-valued operations. If you are using a small computer, the complex operation can be
