1.
By observing three components in wave field space and using analytic signal method,the relationships between complex seixmic signals and characteristic parameters of instantaneous polarization in wave field are given,the corresponding polarized filter is designed,and the satisfactory effects in computer emulation research and measured signal processing are obtained.
通过观测波场空间三个分量，采用解析信号的方法，给出了复地震信号与波场瞬时极化特征参数的关系，设计了相应的极化滤波器，在计算机仿真研究和对实测信号的处理中，取得了满意的效果。
2.
The real part of analytic signal,which gotten by the Hilbert transform is itself.
Hilbert变换而得的解析信号实部为信号本身,虚部为其Hilbert变换,解析信号的幅值即为信号的包络。
3.
The new method calculates the IF from analytic signals corresponding to seismic data by these filters, but the traditional method does it by.
为了改善高分辨地震资料瞬时频率估计的精度,更精细地刻画地下岩性变化和油气空间展布,提出一种基于极平坦有限冲击响应滤波器的地震资料瞬时频率计算新方法,在基于解析信号计算瞬时频率时,用极平坦有限冲击响应滤波器来代替传统的有限中心差分方法(CFDM)中的二阶中心差商。
