最小相位子波的频率域反褶积

本文讨论了在假设子波为最小相位的条件下,频率域时变反褶积的原理与实现的技巧,并提供了用这种方法处理的实例。 本文对实现最小相位频率域反褶积方法的程序粗框图中的一些重要步骤作了说明。 文章还展示了用最小相位频率域反褶积处理的实际剖面,并且将它与时域反褶积的处理作了比较,证明了这二种方法处理效果是一致的,计算频域反褶积的速度则要比计算时域反褶积快。

MINIMUM PHASE WAVELETS DECONVOLUTION IN FREQUENCY DOMAIN

What was introduced here in this paper was the principle and technique of the time-variant deconvolution in frequency domain under the hypothesis of the wavelets being minimum phase. Some important steps about the flowchart in the realization of this deconvolution were described. Examples were given.Sections resulted from this technique were presented and were compared with those resulted from the deconvolution in time domain. The final results show that the effects of these two deconvolution were just the same but the time required for the processing were different, the former was quicker than the later.
