instantaneous phase

Therefore, local wave decomposition technology was introduced into the logging date extrapolation method constrained by time-phase model to gain the seismic instantaneous phase.

为此，在时间-相位模型约束的井资料外推方法中，引入局域波分解技术来求解地震瞬时相位；

Secondly, the technique of profile extraction based on duplicate wavelet transform is used to extract ultrasonic echo signal character owing to the trait of duplicate wavelet transform providing instantaneous phase information and the inherent relation between signal profile and object shape.

然后，根据复小波变换可以提供信号瞬时相位信息的特点，采用了复小波变换提取超声回波包络的方法，并提出一种根据包络线提取物体特征参数的技术；

The appearances of BSRs oon near offset profile, stacked profile, migration profile, migration profile, instantaneous amplitude profile and instantaneous phase profile are compared and described.

比较了近炮检距剖面、叠加剖面、偏移剖面、瞬时振幅剖面与瞬时相位剖面上BSR的显示特征。

It is tried that the instantaneous amplitude, instantaneous phase and instantaneous frequency of seismic information are used for calculating the thickness of the coal seam based on the seismic attribution of various rock formations and the developed characteristics of the coal seam in this area.

根据不同岩层的地震属性及本区煤层发育特点，尝试了利用地震瞬时振幅、瞬时相位和瞬时频率信息计算煤层厚度。

In constant phase correction of seismic record, the phase spectrum plus a constant and the instantaneous phase plus the same constant can bring the same result.

在实现常相位校正时，在记录的相位谱上加一个常数与在记录的瞬时相位上加同一个常数，结果是相同的。
