信号的褶积分解及其在地震勘探中的应用

THE CONVOLUTION AND DECOMPOSITION OF SIGNAL AND ITS APPLICATION TO SEISMIC PROSPECTING

在这篇文章中,我们提出了一个新概念——信号的褶积分解.我们讨论了信号褶积分解的性质,特别是能量有限性质.我们还指出了信号褶积分解在地震勘探中的应用:可以在时间域求取零相位子波的反褶积因子,可以通过时间域方法把一个信号转换为零相位信号.

In this paper, a new concept-the convolution and decomposition of signal is put forward, its nature as well as the limited energy in particular are discussed. Moreover, certain examples illustrating the possibilities of applying the convolution and decomposition of signal to the seismic prospecting are given, such as to determine the deconvolution factors of zero-phase wavelet in time domain and to convert a signal to zero-phage signal by means of time domain method.
