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。
In this paper, we discuss the principle and implementation techniques of time-varying deconvolution in the frequency domain under the assumption that the wavelet is the minimum phase, and provide an example of this method. In this paper, some important steps in the block diagram of the program to achieve the minimum phase-frequency domain deconvolution are described. The paper also shows the actual section of deconvolution with minimum phase frequency domain and compares it with the time domain deconvolution. It proves that the two methods are consistent in processing effect, and the calculation of frequency domain deconvolution Is faster than calculating the time domain deconvolution.
